Re: Question by someone coming from C...
Skye a écrit : Writing this app in Python, not sure what the "best practice" would be. I want a bitfield global logging level that allows me to turn specific debugging modules on and off. If I was doing this in C, I'd just use some globals like: unsigned int debug_level = 0; #define DEBUG_GENERAL 0x0001 #define DEBUG_CONFIG 0x0002 #define DEBUG_OPTIONS 0x0004 etc etc So I guess my questions are: 1. there doesn't seem to be a way to define global constants like in other languages? 2. any special voodoo to use bitfields in Python? Others already gave you the best advises (namely: using the logging module). But let's answer your questions anyway: 1/ by convention, anything named ALL_UPPER is considered a constant. Anyone breaking your code by messing with a PSEUDO_CONSTANT is on it's own and has no right to complain. Consider it as a "warranty void if unsealed" warning. 2/ just use plain integers and bitwise operators. But we're usually more concerned about readability than about saving bits, and I've rarely (maybe twice ?) seen bitfields used that way in Python. -- http://mail.python.org/mailman/listinfo/python-list

Py2exe and name space package
Hi,
I used to freeze my application into Windows executibles using py2exe.
Lately I started using several zope packages in my application, like
zope.interface. Now the freezed program can't run properly. Like the
following example shows:
My setup.py file:
from distutils.core import setup
import py2exe
setup(name='test',
zipfile=None,
console=[
{
'script': 'main.py',
}
])
The main.py test code:
from zope.interface import Interface
print Interface
During the freezing process, the following warning is shown:
*** copy dlls ***
copying
c:\Python25\lib\site-packages\py2exe-0.6.6-py2.5-win32.egg\py2exe\run.exe
-> C:\temp\dist\main.exe
The following modules appear to be missing
['pkg_resources', 'zope.interface']
Running main.exe gives me an import Error.
C:\temp\dist>main.exe
Traceback (most recent call last):
File "main.py", line 1, in
ImportError: No module named interface
What should I do to make py2exe recognize and include zope.interface
in the binary distribution?
Thanks.

authentication work.

DICOM library
Hi everybody! I've been looking for a python library wich allows me to work with with DICOM files, for medical image processing. Finding nothing at first, evenctually i've find the gdcm library, wich is suposed to be for c developement, but they say that you can use it with python, as "It is automatically wrapped to python (using swig)". So, the cuestion is: how can I use this kind of library, wich is suposed to be used with c, in python? When I download the tarball there ae only 2 .py files. shall I install the whole library for using in C, and then try to import the gdcm module in python? becouse i'm afraid it won't work.

You should avoid the use of ``shell=True`` here and use a argument list
instead:
dump = Popen(['dump', '0uaf', '-', '/'], stdout=PIPE)
This results in an exception thrown if the executable doesn't exist. This
exception can be caught and handle for instance with the logging module.
>>> gzip = Popen('gzip',shell=True,stdin=dump.stdout,stdout=PIPE)
Same here, but why don't you use the gzip functionality from the standard
library?

This search option is part of a massive custom tree control that was developed using wxpython. 2. The rest of the tree control is in the form of concepts (labels for the concepts) that the user chooses from to get some text displayed as well. I have been adviced to use AppEngine but do you think that as my application sends a lot of user requests to the server(to ask for some pieces of text to be displayed), using CGI will be too slow? Is there a better way of doing it? If you can advice me on which tools to use to develop my web page that will include a tree structure, I would be very grateful. Thank you very much in advance, Nora. __ Sent from Yahoo! Mail. A Smarter Email http://uk.docs.yahoo.com/nowyoucan.html-- http://mail.python.org/mailman/listinfo/python-list
unable to import modules from other folders
Hi friends I have a module "bigbee" in folder C:\MyDocs\BigBee and another module "foo" needs to import from this.however, "foo" is in D:\foo. foo.py : from bigbee import * The error i get is: ImportError: No Module bigbee. Please provide a solution. -- http://mail.python.org/mailman/listinfo/python-list
Re: unable to import modules from other folders
C:\MyDocs needs to be in the sys.path variable for python to include
it in it's search for modules
Try this:
import sys
sys.path.append('C:\MyDocs')
If you are packaging your program for reuse or later move that folder
bear in mind it will *break*
A better method would be to place the module into site-packages OR in
the same directory as the Py script that uses it.

h2py.py bug?
Hello everyone,
I wanted to use the h2py.py script (Tools/scripts/h2py.py) and it didn't
like char litterals :
Skipping: PC_ERROR = ord()
where my *.h file contained :
#define PC_ERROR '0'
I searched the web and found a post with the same error :
http://mail.python.org/pipermail/python-list/2005-September/340608.html
but it got no replies, I tried the fix and it works. I have the
following questions:
1) Why did it not get any attention, is something wrong with it?
2) If nothing is wrong, did the fix not get applied because a bug report
wasn't filed?
3) Isn't turning a char literal into the ordinal value not contrary to
what a C programmer had in mind when he/she defined it? I mean if you
define a char literal then in python you would have used a string value :
#define PC_ERROR '0'
would become :
PC_ERROR = '0'
in python, and if you intended to use the char type for an 8 bit
numerical value you would have done :
#define PC_ERROR 0x30
where 0x30 is the '0' ascii hex value, so shouldn'it the line in the
diff (see the post) be :
body = p_char.sub("'\\1'", body)
instead of :
body = p_char.sub("ord('\\1')", body)
?
Thank you,
Gabriel

Try profiling it. I'm not an PyInstaller-user, but I could imagine that loading Qt is pretty heavy. So you might try & import as few dependencies as possible, as late as possible.

Hi,
I'm having a bit of trouble with a python script I wrote, though I'm not

The situation is that I'm trying to create a system backup script that
creates an image of the system, filters the output though gzip, and then
uploads the data (via ftp) to a remote site.
The problem is that when I run the script from the command line, it
works as I expect it, but when it is run by cron I only get a 20 byte
file where the compressed image should be... does anyone have any idea
as to why this might be happening? Code follows
#!/usr/bin/python
from subprocess import PIPE, Popen
from ftplib import FTP
host = 'box'
filename = '%s.img.gz' % host
ftp_host = '192.168.1.250'
ftpuser, ftppass = 'admin', 'admin'
dest_dir = '/share/%s' % host
dump = Popen('dump 0uaf - /',shell=True,stdout=PIPE)
You should avoid the use of ``shell=True`` here and use a argument list
instead:
dump = Popen(['dump', '0uaf', '-', '/'], stdout=PIPE)
This results in an exception thrown if the executable doesn't exist. This
exception can be caught and handle for instance with the logging module.
thanks. That exception certainly would have helped me...
gzip = Popen('gzip',shell=True,stdin=dump.stdout,stdout=PIPE)
Same here, but why don't you use the gzip functionality from the standard
library?
is there a way I can create a gzip file-like object which can read the
output from the dump subprocess, and has a read method which outputs the
compressed data, which will not write to disk first? With the above
code python doesn't have to write the system image data to disk at all,
which helps when there is not enough disk space to hold an intermediate
image (at least, that is my understanding of it...).
I had a look at the gzip module, but eventually just fell back to using
the stdin and stdout of a gzip subprocess. I'd be interested to know
how it could be done using the python standard lib though.

Re: Alternative to Decimal type

I came up with a solution long before the introduction of the Decimal type, which has been working well for me. I know the 'scale' (number of decimal places) of the number in advance. When I read the number in from the database I scale it up to an integer. When I write it back I scale it down again. All arithmetic is done using integers, so I do not lose accuracy. [snip] from __future__ import division class Number(object): def __init__(self,value,scale): self.factor = 10.0**scale if isinstance(value,Number): value = value.value / value.factor I think this could lead to trouble. One complaint against binary floating point is that it messes up low-order decimal digits, and this ensures that all calculations are effectively done in binary floating point. Better, I think would be if isinstance (value, Number): self.value = value.value self.scale = scale + value.scale and be done with it. Of course, this means self.scale no longer gives the preferred number of fractional digits. My bias: I did a DecimalFloat class way back when, when Decimal was being discussed, and separated the exponent for calculations from the rounding precision for display. What about a little rewrite so the current implementation is like the original, and all calculations are done as integers? Or is this just getting closer and closer to what Decimal does?

I include the lxml package in some of my programs and I do so by
adding the following to the setup.py
packages = ['lxml']
However, I'm not sure if what you want to add is truly a package.
Yours might go into the "includes" directive. Currently, I use the

Determining which things in 'from package import *' are actually used
I have a fairly large library of Python code, where 'from package import *' is used rather liberally, and it's not uncommon for more than one of these to appear in any given module. What I'd like to be able to do is to clean my code up a bit and turn each of the 'from package import *' statements into 'from package import thing_1, thing_2, ..., thing_n', where only thing_i's that are actually _used_ in the module are imported. In this way I hope to make my code a bit more understandable by future civilizations. :) (it needs all the help it can get!) Does anyone know of a package/recipe/whatever that does something like this automatically, even in limited cases? Ideally it should be accomplished only by looking at the source, or at most, importing the module. TIA, -Pat -- http://mail.python.org/mailman/listinfo/python-list

use
float("123.45")
to convert a string to a float.
Of course you need to do that on all your elements above by e.g. a
list-comprehension.

Instructions on how to build py2exe 0.6.8 (or an installer would be nice, too!)
Hello, I'm trying to build an executable with py2exe, but unfortunately the version I have is 0.6.6, which has a rather annoying bug that doesn't let you rename the executable file if you bundle everything in a single executable. It seems fairly unacceptable to tell our customers that they can't rename a file we send them. I hear this problem is fixed in 0.6.8, but unfortunately there's no standalone installer for py2exe 0.6.8 - the most recent version that has an installer is 0.6.6 way back from 2006 (!). Is there a standalone installer for py2exe 0.6.8 anywhere? If not, how do I build it from source? (There's no instructions in the readme - it just says "How to install: download the standalone installer" and doesn't include building instructions.)

proposal: give delattr ability to ignore missing attribute
I would like to propose that functionality be added to delattr to handle the case when the attribute does not exist. First off, getattr handles this nicely with the default parameter: value = getattr(obj, 'foo', False) instead of: try: value = getattr(obj, 'foo') except AttributeError: value = False or: if hasattr(obj, 'foo'): value = getattr(obj, 'foo') else: value = False And I think it makes sense to have something similar for delattr (name the argument as you wish): delattr(obj, 'foo', allow_missing=True) instead of: try: delattr(obj, 'foo') except AttributeError: pass or: try: del obj.foo except AttributeError: pass or: if hasattr(obj, 'foo') delattr(obj, 'foo') For backwards compatibility, allow_missing would default to False.

Dumb idea?
Hi everyone - I like playing around with language syntax and semantics. I'm thinking about pulling down the PyPy code and messing around to see what I can accomplish. My first idea is most succinctly described by example: class IBlockProtocol: def __block__(self, func): # NO RETURN VALUES! pass # my_IBlockProtocol is an expression that evaluates to an implementor of IBlockProtocol my_IBlockProtocol: expr # becomes: my_IBlockProtocol.__block__(lambda: expr) ### my_IBlockProtocol: expr # becomes: my_IBlockProtocol.__block__(lambda param1, paramN: expr) ### my_IBlockProtocol: stmt1 stmt2 # becomes: def anon(): stmt1 stmt2 my_IBlockProtocol.__block__(anon) ### my_IBlockProtocol: stmt1 stmt2 # becomes: def anon(param1, paramN): stmt1 stmt2 my_IBlockProtocol.__block__(anon) ### Has this already been done? Is it a stupid idea? I think it could be used to simplify event handling and some Twisted stuff. I'm mainly looking for reasons why I _wouldn't_ want to take the time to get my hands dirty with the PyPy code (or even CPython) and try to implement this syntax. Thanks.

Easy - download the sources, and enter 'python setup.py bdist_wininst' in the top-level directory. You need the same compiler that was used to build the Python that you use.

If I do the next :
t1 = [(round(float(x),1), round(float(y),2)) for x, y in t]
I get the long float as :
[(35.797, -0.23999), (33.297,
-2.71), (33.601,-2.4199)]
But I would have a float with 2 decimal numbers.

Advice for a python newbie on parsing whois records?
Hi. I'm stretching my boundaries in programming with a little python shell-script which is going to loop through a list of domain names, grab the whois record, parse it, and put the results into a csv. I've got the results coming back fine, but since I have *no* experience with python I'm wondering what would be the preferred "pythonic" way of parsing the whois string into a csv record.

Whether Apache 2.0 is GPLv2 compatible or not is irrelevant, GPL is only one type of license, no more no less, it's not the Holy Grail of free software spirit. The fact that many other softwares use GPL license is because the license has been designed for general use and many open source groups doesn't really have the knowledge, capability, and/or time to create their own license (creating a license is not as easy as it seems), most doesn't even care what their software is licensed on and their exact terms. The use of a well-known license also made it easy for the users to know the license he's agreeing to without reading and reading and reading a license again and again and again. -- http://mail.python.org/mailman/listinfo/python-list

There is no such thing as a float with only two decimal numbers. This has been discussed on this ML a bazillion times - what you see above are rounding errors due to the approximation of decimal values by binary floating points. You can *convert a float to a string* and specify a precision when printing: >>> print "%.2f" % 2.41999 2.42 Or you can use the module decimal to work with numbers base 10 - which you can also limit to certain precisions.

Generally, when doing a simple parsing you'd use re module (regular expression). More complex parsers would use pyparsing (3rd party module). I've never used pyparsing myself though.

This does not affect the distinction between a SERVICE that has it's own terms and conditions with a SOFTWARE that provides the means to use that service from a programmers or users point of view.

Well I can see a few problems here.
First is that putting percent signs around the whole path is
never going to work anyway. You want something like:
"%USERPROFILE%/dir/file".
Secondly, the expansion of environment variables like
USERPROFILE is done for you by the shell or the command
prompt. You have to do it for yourself if you're opening your
own files. You want something like:
import os
print os.path.getmtime (os.path.join (os.environ['USERPROFILE'], "ntuser.ini"))
But finally, what do you mean "run on machines where the username is
unspecified"? If you mean: where no user is logged in, then you won't
have a (meaningful) userprofile in any case: it might be the Default User
profile; I'm not sure. But is that what you want?
You *can* use the functions in the win32profile module of the pywin32
packages to find out various things about profiles directories, but things
can get quite complicated if users have roaming profiles and the like.

problems with opening files due to file's path
Okay, so what I want my program to do it open a file, a music file in
specific, and for this we will say it is an .mp3. Well, I am using the
system() command from the os class. The problem I am running into is that
when I send the path of the file to the system() command, which for those of
you who don't know the system command is the equivalent of typing one
command into command prompt or terminal depending on your system. But let's
say that the file is "C:\Music\01 - Track.mp3" or something like that where
the number 0 is next to the backslash. Another example is this
"C:\Music\track(single)\Track.mp3" The problem here is that the ")" at the
end of the single, is conflicting with the backslash as well. Now here is
the exact code I was trying to do and when I run it I get false returned.
system("\"C:\Documents and Settings\Alex\My Documents\My
Music\Rhapsody\Bryanbros\Weezer\(2001)\04 - Island In The Sun.wma\"")
Okay, now as you can see it sends it to the system with quotes "\"" and
works if I change the file path and get rid of the "04" and the ")" it
works, so that is the problem no doubt. If anyone has a way to do this
please let me know, or even another way to open a music file like this.
Help?

Yeah. You need to either double all the backslashes or make it a raw
string by adding an "r" to the beginning, like so:
os.startfile(r'C:\path\to\my\file')

Tim,
I'm surprised you didn't mention your excellent winshell utility. I
use it for this sort of issue all the time where I need to update
files on login and I don't know the user's name beforehand.
The winshell.Desktop() one has been a life saver and I think the OP
could probably use winshell for their problem. Or I may be completely
off my rocker.
Either way, here's the link: http://timgolden.me.uk/python/winshell.html

Re: problems with opening files due to file's path
Well, now i've hit another problem, this time being that the path will be a
variable, and I can't figure out how to make startfile() make it raw with a
variable, if I put startfile(r variable), it doesn't work and
startfile(rvariable) obviously won't work, do you know how to make that work
or better yet, how to take a regular string that is given and make every

On Jun 10, 1:04 am, Bruno Desthuilliers wrote: > If you hope to get a general agreement here in favor of a useless > keyword that don't bring anything to the language, then yes, I'm afraid > you're wasting your time. Actually, what I hope to do is to "take something away" from the language, and that is the need to clutter my identifiers with leading underscores. I find that I spend the vast majority of my programming time working on the "private" aspects of my code, and I just don't want to look at leading underscores everywhere. So I usually just leave them off and resort to a separate user guide to specify the public interface. I'll bet many Python programmers do the same. How many Python programmers do you think use leading underscores on every private data member or method, or even most of them for that matter? I'll bet not many. (See the original post on this thread.) That means that this particular aspect of Python is basically encouraging sloppy programming practices. What I don't understand is your visceral hostility to the idea of a "priv" or "private" keyword. If it offends you, you wouldn't need to use it in your own code. You would be perfectly free to continue using the leading-underscore convention (unless your employer tells you otherwise, of course). I get the impression that Python suits your own purposes and you really don't care much about what purpose others might have for it. I am using it to develop a research prototype of a major safety-critical system. I chose Python because it enhances my productivity and has a clean syntax, but my prototype will eventually have to be re-written in another language. I took a risk in choosing Python, and I would feel better about it if Python would move up to the next level with more advanced features such as (optional) static typing and private declarations. But every time I propose something like that, I get all kinds of flak from people here who do their hacking and care little about anyone else's needs. With a few relatively small improvements, Python could expand its domain considerably and make major inroads into territory that is now dominated by C++, Java, and other statically compiled languages. But that won't happen if reactionary hackers stand in the way. Side note: I've been looking at Scala, and I like what I see. It may actually be more appropriate for my needs, but I have so much invested in Python at this point that the switch will not be easy. -- http://mail.python.org/mailman/listinfo/python-list

"~" appears to look first at the HOME environment variable.
That is not necessarily the same as "USERPROFILE". On my machine it is
not.

Yeah. You need to either double all the backslashes or make it a raw
string by adding an "r" to the beginning, like so:
os.startfile(r'C:\path\to\my\file')

If you use the google appengine you probably won't have problems with performance. Django [1] works with the appengine (as far as I know) so you can build your app using that framework. If you don't insist on the appengine you may want to check out turbogears [2] either the stable version 1 [3] or the brand new but not yet released version 2 [4]. If you don't mind a steep learning curve there is zope [5] but many tend to agree that for anything small to medium size it's an overkill. If your app is really simple and any framework feels too heavy weight you might just go ahead with plain CGI or fastCGI or use mod_wsgi [6] directly assuming you use apache. The old mod_python [7] module of apache is not very actively maintained and mod_wsgi is favored over it but if what you do is a small in-house stuff nobody will stop you from using it and it can actually be a good option.

Re: Why does python not have a mechanism for data hiding?
Hi Russ, Here are just some pragmatic considerations. Personally I am against data hiding, but I obviously won't convince you in that regard. There are some pros and cons as with anything, and I feel the cons outweight the pros (namely that users of code should be able to use how they want, even if it means shooting themselves in the foot; and the fact that priv somewhat breaks the dynamics of python) Even if your proposal were to go through, you are looking at probably 2 years before it can even be used. Python3 is basically in freeze mode, and it contains the biggest change in python syntax for a long time. I know it doesn't seem like a big change to you to add a priv keyword, but python very rarely adds keywords, so it's a long shot merely for that reason. This is something that potentially would be under consideration for something like 3.2 or higher I think, so if you want to get the job done now, this topic or trying to convince other long time python users isn't going to accomplish your goals. Leading underscore takes two keystrokes to type (shift, _) while priv, private, etc takes many more. If you are too lazy to type "_var" then how come you aren't too lazy to type "priv var"? Too me it seems like more typing. If the primary objection to leading underscores is looks, it seems like you unnecesarily avoid them for a pointless reason. There are ugly aspects to every language, and there isn't really a better convention to use that I can see. Without of course implementing keywords, which are conceptually difficult to think about in terms of python object model - although you might be able to come up with a way. But if you have a better naming convention or strategy that you want to try on your code, nothing is stopping you. You can use one of the hacks found in this thread, or come up with your own hack, to more or less accomplish what you want. It should take 30 minutes or less to set up, and you are done with it. The internals of python make it difficult to do more than that, but you are welcome to create your own python fork if you think you are up to it. Although I think that would be more than 30 minutes of work. And feel free to try other languages. No one claimed python is the best for every circumstance. Well, if someone claimed that they are just fooling themselves. Python is a good hacker language that scales pretty well into enterprise and web services; and can be used for other things as well. I don't believe that data prevention (we aren't really talking about just hiding here) is necessary for 99% of tasks, but other people think differently, so there are plenty of languages that implement these features. Good luck finding a solution to fit your project. However I don't think trying to get a "priv" keyword into official python is feasable unless you want to wait a very long time and go hoarse from shouting :) -- http://mail.python.org/mailman/listinfo/python-list
Re: problems with opening files due to file's path
That would work, but not for what I want. See the file could be anywhere on the user's system and so the entire path will be unique, and that didn't work with a unique path.

But every time I propose something like that, I get all > kinds of flak from people here who do their hacking and care little > about anyone else's needs. Let me share my personal insight. I used Python for a mission-critical application that needed, in effect, almost 100% uptime with superior throughput. In other words, it was a very fine piece of art that needed to be precise and correct. In the end, Python delivered, under budget, under schedule, and with superbly low maintenance costs (practically 0 compared to other systems written in Java and C). I didn't have to use any of the features you mentioned, and I can't imagine why you would need them. In fact, having them in the language would encourage others to use them and make my software less reliable. You may think we are all a bunch of hackers who are too stupid to understand what you are saying, but that is your loss. Now, let me try to explain something that perhaps the previous 166 post may not have thoroughly explained. If I am duplicating what everyone else has already said, then it's my own fault. Short answer: You don't need these features in Python. You do need to use the right tools for the right tasks. Long answer: Who cares what the type of an object is? Only the machine. Being able to tell, in advance, what the type of a variable is is a premature optimization. Tools like psyco prove that computers (really, programmers) nowadays are smart enough to figure things out the right way without any hints from the developer. Static typing is no longer necessary in today's world. Who cares about private declarations, or interface declarations at all? It is only a message to the developers. If you have a problem with your users doing the right thing, that is a social problem, not a technical one, and the solution is social, not technical. Yes, it is work, but it is not coding---it is explaining to other living, breathing human beings how to do a specific task, which is what you should have been doing from the start. When all you have is a hammer, the world seems full of nails. Think about that. You have more tools than Python to solve these problems, and Python will never be the panacea you wish it was. The panacea is you, putting the right tools to use for the right tasks. -- http://mail.python.org/mailman/listinfo/python-list
Re: problems with opening files due to file's path
heh thanks Mike - glad im not going mad :P
Just tested locally in IDLE (I know I know!) and it works for me like this:
test = os.path.join(os.getcwd(),"NEWS.txt")
test
'D:\\Python25\\NEWS.txt'
os.startfile(r"%s"%test)
And the file opens...
Does the file definitely exist?

Yeah. You need to either double all the backslashes or make it a raw
string by adding an "r" to the beginning, like so:
os.startfile(r'C:\path\to\my\file')

What I'd like to be able to do is to clean my code up a bit and turn each of the 'from package import *' statements into 'from package import thing_1, thing_2, ..., thing_n', where only thing_i's that are actually _used_ in the module are imported. In this way I hope to make my code a bit more understandable by future civilizations. :) (it needs all the help it can get!) Does anyone know of a package/recipe/whatever that does something like this automatically, even in limited cases?

That is not necessarily the same as "USERPROFILE". On my machine it is

There was quite a debate over that on python-dev earlier

"~" means on a Windows box. The implementer of that patch
took the view that HOME comes first and then USERPROFILE,
finally HOMEDRIVE/SHARE/PATH. On my machine at work,
the latter should take precedence as they are set via
my domain logon. Other people's mileage may vary. In addition,
the code assumes that the home for any *other* user can
always be derived from the *current* user's home.
Which will not always be the case.
All that is essentially why the user-specific functions

Contrary to what other posters have asserted, doing the above can't make
a difference. Putting 'r' in front of a string literal tells Python not
to give backslashes in the string literal any special treatment. Since
there are no backslashes in "%s", the 'r' does nothing.
Therefore, (r"%s"%full) is the same as ("%s"%full), which is the same as
(full), assuming that `full` is the name of a string.
The real answer lies in fixing the code where you're assigning the
pathname to 'full', which you haven't posted. Please post the code where
you're assigning the pathname, or better yet, post the complete code
you're running.

I assumed the OP was trying to do the string substitution within a

Although in theory you could get any exception at any point, in practise you shouldn't unless your program is broken. If it is broken the exceptions shouldn't be caught and should cause the program to terminate, so the harm is reduced. The exceptions that should happen (such as IOError) should be from predicted points, and anticipated. A notable exception is MemoryError, which can show up from anywhere at any time. Nobody's come up with a solution to that one, so we usually just let the program die. Cancelling a thread implies your program will continue.
