You can process XML data with Python as long as you can get it - you
will be able to do what you want with it.

How do you access your remote file ?

Is any way to split zip archive to sections?

[Durumdara]

Hi!

I want to create some backup archives with python (I want to write a backup
application in Python).
Some package managers (7z, arj, winzip) can create splitted archives (1
mega, 650, 700 mega, etc).

Because I want to ftp these results to a ftp server, I want to split large
volumes to 15 mb sections.

Can I do it with any python wrapper automatically (like in Cobian), or I
need to create the large volume, and next split it with another tool?

Or anybody knows about a command line tool (like 7z, or arj) that can expand
the splitted archive (and I can add files with them from Python one by one)?

So what is the solution?

Thanks for your help:

I second this (or third or whatever if my post is slow).
It is tremendously useful to start something and to be told it has timed
out by a call, rather than to have to unblock the i/o yourself and
to "busy-loop" to see if its successful.  And from what I can see
the select functionality is not much different from busy looping...

Hint: extend[0]  is1.1

Hint: 2.1 is less than 4

You have to stop counting and come out of the loop when you find the 
first one - what your function is doing is counting the elements less than
num, not finding the first one that is.

The reason I asked is that I have noticed that other file like objects
(on Suse 10 Linux and Python 2.4 out of the box) aren't  really:

If you start a blocking read in one thread on a serial port, and you
then issue a write in another thread, the characters are not transmitted
until the read completes.  It is as if the "driver" gets busy in the read
and queues the write - I think a lot of the "My output does not come
out till I close the programme" type of questions on this group is
caused by this.   And calling flush makes no difference under these
circumstances.- you have to unblock and use try - except on the read
as well.

So I was wondering if sockets are the same, as I haven't messed
with them much- just set up simple client server stuff in a
"Monkey see, Monkey do" way.

: - ) Yes the UTP allows point to point full duplex, as there are separate
receive and transmit pairs.

But the protocol is not called Carrier Sense Multiple Access with
Collision Detection for nothing. - there can be no collisions in a true
full duplex channel. And its kind of difficult to swap rx and tx pairs
if there are more than two endpoints - you need a central point, and then
the "slaves" can't hear each other unless the central point passes the
messages on, or does some switching functions.

Reason I mentioned Ethernet is that in most cases (between machines)
its the underlying technology and if sockets were therefore not actually
full duplex it would not be surprising.

Is it actually possible to do what I have described for the serial port
case on a socket and have the message transmitted before one is
received?  Using a blocking receive?

Er. How about

 StringBuffer c = a + b;

Indentation for code readability

[DE]

Hello,

Here is what I do in C++ and can not right now in python :

pushMatrix()
{
 drawStuff();

 pushMatrix();
 {
drawSomeOtherStuff()
 }
 popMatrix();
}
popMatrix();

The curly brackets have no functional meaning but increase the
readability significantly. I want to be able to do the same thing in
python. Since curly brackets are not available and indenting without
an if or while conditional doesn't work, I have started to question if
this is possible in python at all.

Any ideas ?

I've been thinking about that for some minutes now and I have doubts
that it will increase the readability. Maybe for you as you invented
that style but not for others.
There are a few standards for formatting C code and even this few have
cause many discussions between developers.
Python has one convention (defined in PEP 8) and the deeper you dive
into the language the more you will like it.
BTW: having one way to do it is one of the main ideas of Python's
philosophy.

You *can* use round brackets and/or square brackets. E.g.

def pushMatrix():
drawStuff()
pushMatrix()
(
drawSomeOtherStuff()
)
[
drawEvenMoreStuff()
]
popMatrix()

Whether you *should* do that is a different question ... It's a bit

You could use

if True:
# do stuff

but I have no sympathy for such self-inflicted noise.

With Python 2.5 you can do even better -- you can emulate what should have
been RAII in your C++ example in the first place:

from __future__ import with_statement

from contextlib import contextmanager

def push_matrix():
print "push"

def pop_matrix():
print "pop"

@contextmanager
def matrix():
m = push_matrix()
try:
yield m
finally:
pop_matrix()

with matrix():
print "do stuff"
with matrix():
print "do more stuff"

It was said that the setuptools stuff could work with simple package

So posix has this great abstraction around places data can come from and go
to, file descriptors.  But actually it's not so great, because it leaks all
over the place.  Oh well.

Once you get to this level of detail (ie, "is it full duplex?"), then you
really do have to be thinking about what's behind the file descriptor.  A
serial port _can_ be full duplex, but isn't always.  Other kinds of file
descriptors might also be full duplex or they might not be.  It just depends
what the file descriptor really is.

Fortunately for us though, TCP sockets are full duplex. :)  Of course, maybe
"full duplex" is an over-simplification.  What does it really mean, anyway?
Does it mean that you can always read at the same time as you are writing?
What does "at the same time" mean anyway?  Oh well, I can just keep assuming
it's just a sort of vague hand-wavey feature. :)

I'm going to keep saying yes here, but it's hard to explain why without
agreeing on a really detailed definition of "full duplex" and then most
likely also talking about a bunch of things below the TCP interface to
sockets.

I wouldn't assume that - it could be a python on a platform without threads.

I really don't think that your idea is worth the effort. If there is 
something that can be safely interrupted at any given point in time - 
which is the exception, not the rule - then one can "code around" that 
missing feature, by spawning a subprocess python, using pyro to 
communicate, and terminate it. I've done so before.

Some people here said "we're adults, we make sure our code will be 
safely interruptable". But first of all, even adults make errors, and 
even more important: most of the time such a feature is wanted, it's 
about limiting some scripts that come from an untrusted source - like 
user-written plugins. Such a feature would encourage people to use it in 
such cases, but not stand up for the nastiness it may provoke.

Sending emails to 3 addresses....

[Boudreau, Emile]

Hello all, I'm trying to send a results email to 3 people. For some
reason only the first person in the list will receive the email but in
the received email it shows the 3 addresses. Here is my code, can
someone show me where I'm going wrong?? Thanks

sendMail('this is the subject line', 'the results: 71 fails, 229 pass,
300 total.', '[EMAIL PROTECTED], [EMAIL PROTECTED],
[EMAIL PROTECTED]')

def sendMail(subject, body, TO, FROM="[EMAIL PROTECTED]"):
print TO
HOST = "exchange.mycompany.com"
BODY = string.join((
"From: %s" % FROM,
"To: %s" % TO,
"Subject: %s" % subject,
"",
body
), "\r\n")
server = smtplib.SMTP(HOST)
server.sendmail(FROM, [TO], BODY)
server.quit()

That's weird. How on earth does that happen?

But if an object can be garbage collected before the is operator does the

Emile,

You are passing the TO addresses as 3 addresses in a single string.
[TO] results in a list containing a single string - not a list
containing 3 individual addresses.

You need to either pass the addresses to the function as a list
containing the 3 addresses as individual strings,  or change

[TO]

to

TO.split(',')

The lifetimes of the two objects createted in the first comparison do 
not overlap: once the call to id() returns it immediately drops the 
reference to its parameter. Python's memory allocation has a tendency to 
reuse memory immediately so the second call to object() creates another 
object at the same location.

In the second comparison neither object can be released until the 'is' 
operator returns a result, so there is no memory reuse.

The objects compared using the is operator have at least one reference, 
so they cannot be subject to garbage collection.

You might get some risky situations if you bring weakrefs into the mix. 
For example de-referencing two weak references to different objects both 
of which get garbage collected compares True because both references now 
return None.

>>> c1, c2 = C(), C()
>>> r1, r2 = weakref.ref(c1), weakref.ref(c2)
>>> r1() is r2()
False
>>> del c1
>>> del c2
>>> r1() is r2()
True

I don't understand why you are indenting

Thank goodness it isn't, in general.

But if you want people to point at you and laugh in the street, you can do
this:

pushMatrix()
if True:
drawStuff();

pushMatrix();

drawSomeOtherStuff()

popMatrix();

popMatrix();

Thanks !

Any parsing library I used before were heavy to start with.
The benefit was inversely proportional to the size of the project.
Your look to be lighter, and the results are more easily usable.

Thanks for showing me your lib.

Anyway today I will keep my idea for small parsing.

If I understand this contortion is because you have some sort of stack 
and you want the code to follow the depth as you push and pop things 
from the stack.

If you write this in Python then when drawSomeOtherStuff() throws an 
exception your 'stack' will get messed up, so you'll need to add some 
more code to handle this. Using Python 2.5 this is the sort of thing you 
should end up with (and you'll notice that your indentation appears 
naturally when you do this):


from __future__ import with_statement
from contextlib import contextmanager

# Dummy functions so this executes
def pushMatrix(arg): print "pushMatrix", arg
def popMatrix(arg): print "popMatrix", arg
def drawStuff(): print "drawStuff"
def drawSomeOtherStuff(): print "drawSomeOtherStuff"

# The matrix stack implemented as a context handler.
@contextmanager
def NewMatrixContext(arg):
pushMatrix(arg)
try:
yield
finally:
popMatrix(arg)

# and finally the function to actually draw stuff in appropriate
# contexts.
def fn():
with NewMatrixContext(1):
drawStuff()
with NewMatrixContext(2):
drawSomeOtherStuff()

fn()

The indentation of function calls increases readability not in the
sense that it is easier to decrypt the code, but rather it is
analogous to the coordinate system transformations these matrix push
and pop calls perform..

Yes, just like C's -- see point 4 in the "Spirit of C" summary taken

"Curly brackets have no functional meaning"?  Surely you must be
thinking of C, but not C++.  Some of the most powerful idioms (idia?)
of C++ make use of functionality that runs when a closing bracket
causes local variables to fall out of scope.  In fact, this technique
is crucial to writing exception-safe code.

The most obvious has to do with memory allocation/deallocation, and
the STL template .   was invented to prevent this
problem:

{
// create a pointer - let's pretend I need a pointer
// and can't just allocate blah as a local SomeObject
SomeObject* blah = new SomeObject();

// do something with blah
blah->doSomething();

// do something else - OOPS! exception happened
blah->doSomethingBad();

delete blah;  // never got here - memory leaked
}

Instead, define blah using :

{
// create a pointer - let's pretend I need a pointer
// and can't just allocate blah as a local SomeObject
auto_ptr blah ( new SomeObject() );

// do something with blah
blah->doSomething();

// do something else - OOPS! exception happened
blah->doSomethingBad();

// but we don't care because when auto_ptr goes out
// of scope, it deletes its pointers allocated
// memory
}

I was on one C++ project in which our coding guidelines said something
to the effect of "no delete statements except in cleanup templates,"
meaning that all allocated variables had to be wrapped in some form of
auto_ptr template to ensure resource release on delete, even in the
face of exceptions.

So that closing '}' actually DOES do something functional, in running
the destructors of all locally declared variables.

But why should Python folks care, since garbage collection takes care
of our basic memory needs without all this auto_ptr stuff?
Well memory allocation is only one of these symmetric function cases.
Garbage collection doesn't do anything for us in:
- database transaction commit/rollback
- mutex lock/unlock
- web client session close/release
- release of any other kind of allocatable resource

AND, it does this deterministically, not "at some possible time in the
future" like GC.
(Yes, I know that CPython's ref counting scheme *does* release memory
immediately, but this is an implementation-specific behavior.)

Prior to Python 2.5's "with" construct, the closest Pythoners could
get was to use try/catch/finally, and put the resource release code
into the finally block.  There are also some decorators on the Python
wiki that encapsulate this "be sure to close the door" logic into some
friendlier syntax (even if it does use that ugly '@').

I agree but for monitoring...

I've had good luck with executing a popen to grab and parse output
from ps -Af and pass it your own process ID as the search. It adds
overhead to the cpu exec time but it is much less than 1sec so you
won't see it.

Inserting '-' character in front of all numbers in a string

[kevinliu23]

Hey guys,

I want to be able to insert a '-' character in front of all numeric
values in a string. I want to insert the '-' character to use in
conjunction with the getopt.getopt() function.

Rigt now, I'm implementing a menu system where users will be able to
select a set of options like "2a 3ab" which corresponds to menu
choices. However, with getopt.getopt(), it'll only return what I want
if I input -2a -3ab as my string. I don't want the user have to insert
a '-' character in front of all their choices, so I was thinking of
accepting the string input first, then adding in the '-' character
myself.

So my qusetion is, how do I change:

"2a 3ab" into "-2a -3ab".

Regular expressions? :/

New to Python - Easy way to open a text file

[Max Steel]

Hey gang, I'm new to python coding.  I'm trying to find the simplest way to 
open a text file (on the same server) and display it's content.

The text file is plain text (no markup language of any kind).

The filename gets found and placed into a variable named [plainfiles.href]

I'm using python to find the text files, and a .ezt template to display the 
list of the files.  But I can't figure out how to read the contents of the 
file, and display it within the same template.

Any help is appreciated.

Thanks in advance,

Regular expressions would definitely work. Here's a hack though:

tempInput = '2a 3ab'
tempLst = tempInput.split(' ')

output = ''
for i in tempLst:
   output += ('-' + i + ' ')


I'm sure there are many better and more elegant hacks than this.

 You can do simple games without programming.
 There's a graphical integrated environment.
 Programs can be written in Python.
 There's a published book ("Blender GameKit")
 German documentation may be hard to come by, though.

I'm not familiar with ezt formats, however reading a text file is a
breeze.

f = open(r'pathToFile')
while True:
line = f.readline()
if not line: break
# do something with the line of text such as print it.

f.close()


I suppose you could write it to .ezt? Maybe you need to format each
line before inserting it. I hope this points you in the right
direction anyway.

Fair enough.  

Did you intend to suggest "ps -F"?  While ps remains not-so-well
standardized, I know of no version where "ps -Af" details *memory*
usage.

Parsing can be simplified with such invocations as
ps -o pid -o rss -o size -o cmd
(which can itself be rewritten in various ways, depending on the
flavor of ps involved).

Groups are numbered left-to-right irrespective of the expression
contents.
I am quite happy with the names being merely apseudonym for the
positional
group number and don't see a problem with not allowing multiple
occurrences of  the same group name.
I did see some article about RE's and their speed. It seems that if
Pythons
RE package distinguished between 'grep style' RE' and the full set of
Python
RE's then their are much faster and efficient algorithms available for
the
grep style subset.

Breaking my silence on 9/11 Truth

by John Kusumi Page 1 of 1 page(s)

http://www.opednews.com


Tell A Friend

Initially I preferred to keep silent about the 9/11 Truth Movement, to
not be diverted from my issue. I've been associated with the China
Support Network, being its founder, and in recent years, I give my
speeches in that vein exclusively. That means, I have a cause and I
don't need a spare cause, nor a soapbox, nor a reason to be known in
the public discourse, where I've contributed since 1980. My 9/11
article is written, not oral; in any public appearance, I remain on
the China issue. The article is volunteered and not sponsored; I
simply think it fair to have the question, "What happened on 9/11?",
and to have the indicated investigation that is genuine and impartial,
rather than a whitewash. Read on, to where I suggest a role for Glenn
Beck and Bill O'Reilly.

Recently, Rosie O'Donnell raised the issue of 9/11 Truth, questioning
how one or more of the buildings fell in New York City on September
11, 2001. Also, actor Charlie Sheen has come out with his own
questions and concerns about what happened that day, and we've learned
that he will narrate an updated version of Loose Change, a documentary
that questions the official story of 9/11. This led to mentions on
television by Bill O'Reilly and Glenn Beck, top conservative
commentators who seem to have replaced George Will and Bob Novak.
(Note to youngsters: The latter were leading conservative commentators
in the post-Watergate period. What's Watergate? Check Wikipedia.)

I cannot be counted a fanatic on the issue of 9/11 truth. I do my
share of writing, publishing, and speaking; and, but for one related
blog post, this is my first article on the subject. The standard that
I would like to uphold is truth, period -- something that all should
care about, and that journalists in particular should be finicky to
discern and record accurately. The field of journalism at least bills
itself to be concerned about non-fiction and a first draft of history.
I believe that non-fiction and truth are synonyms, and that to sweat
these details ought to be right up the alley of U.S. journalists.

Imagine if you will a bumper sticker that says: "Pearl Harbor:
Roosevelt Knew." In the 1940s, there were many very staunch, patriotic
citizens, who likely had full faith in their President Roosevelt (FDR)
and for whom our hypothetical bumper sticker may hurt, or sting
deeply. The sticker could be rejected on the simple basis that it is
alien to the world view, held by those observers, of FDR as an upright
and above-board U.S. President. More recent research, however, has
convinced many historians that the sticker is indeed accurate. I
believe that even our mainstream commentators have allowed the same,
so that we now have an accepted view of history, to wit that Roosevelt
had foreknowledge of the Japanese attack at Pearl Harbor. If so, then
the truth behind Pearl Harbor becomes LIHOP -- Let It Happen On
Purpose.

The above paragraph does NOT prove anything about 9/11. If people make
bumper stickers saying, "9/11: Bush Knew," then they still must make
their case. For those who assert provocatively, there is an onus or a
burden of proof. Words are not "more true" on a bumper sticker, and
"less true" elsewhere. The standard of proof is not in the placement
of the words. However, I believe and would stand behind a bumper
sticker that said: "Tiananmen Square: Bush Knew." (That refers to the
elder President Bush, who gave a nod and a wink to Chinese leaders
before their troops went to Tiananmen Square. Chinese leaders MIHOP --
Made It Happen On Purpose.)

For those who are toying with the possibilities, alternate
explanations for 9/11 include (a.) "we were surprised -- they got one
by us (totally innocent);" (b.) "we were warned, but we failed to
connect the dots (totally incompetent);" (c.) LIHOP (partial inside
job, partially sinister); and (d.) MIHOP (an inside job, totally
sinister). The official explanation has already migrated, since the
early days, from (a.) to (b.). Perhaps one reason why I've avoided
9/11 Truth as a topic is due to its parallel with rejecting the
"Roosevelt knew of Pearl Harbor" thought, as above. Explanations (c.)
and (d.) for 9/11 entail the culpability of someone in our own
government. It is alien to the world view that the U.S. Government
protects Americans. In this case, Americans were harmed by
perpetrators who were clearly evil, and it is harsh -- indeed
anguishing -- to contemplate the case if it were that the hand of evil
was partly domestic. Culpability within our own government would make
9/11 the crime of the century.

I will not take up the job of re-iterating the case that's been made
by the 9/11 Truth Movement. But, increasing numbers of questions have
been uncovered, and the awareness of prior warnings, given to the U.S.
government in advance, has incr

If you like optparse, you should try argparse:

 http://argparse.python-hosting.com/

It has an optparse-style API, along with support for

* positional arguments
* sub-commands
* required options
* options with a variable number of args
* better usage messages

clean up html document created by Word

[jd]

I am looking for python code (working or sample code) that can take an
html document created by Microsoft Word and clean it up (if you've
never had to look at a Word-generated html document, consider yourself
lucky ;-)  Alternatively, if you know of a non-python solution, I'd
like to hear about it.

Thanks...

You could try Beautiful Soup at 
http://www.crummy.com/software/BeautifulSoup/documentation.html

Python is good for parsing HTML/XML, so you could also try googling
Python parsing as well.

IIUC, the original poster is asking about 'cleaning up' in the sense
of removing the swathes of unnecessary and/or redundant 'cruft' that
Word puts in there, rather than making valid HTML out of invalid HTML.
Again, IIUC, HTMLtidy does not do this.

If Beautiful Soup does, then I'm intererested!

It's not an easy job, and it may require some manual editing, because
that html is the worst I have seen. You can use Tidy, there is a GUI
too, and you can use its suggestions to manually remove the offending
things, at the end Tidy is able to digest it, and return a cleaned up
html. But then you have just started, you need to process it even
more.

A solution is to avoid creating the Html in the first place, or to use
something more like Word 97 to create it. Dreamweaver too is able to
help with Word2000+ trashy html, but usually not enough.

If the structure of the Html document is simple enough, and assuming
you are using Windows, you can open it with Word, save it as RTF,
reopen it with Wordpad, save it again to remove some trash, and then
use something else (like Word 97, or maybe even Aracnophobia, etc) to
convert it to Html. Generally I've never found a really good way to
convert Rtf to a very good Html.

I was using that article to help me.  My problem was I was trying to
implement smeth() as a function rather than a class.  I hacked around
some more, and I came up with the following before peeking at this
thread for the answer:

class smeth(object):
def __init__(self, func):
self.func = func

def __getattribute__(self, name):
print "smeth -- getattribute"
return super(smeth, self).__getattribute__(name)

def __get__(self, inst, cls=None):
print "smeth get"
return self.func

class Test(object):
def __getattribute__(self, name):
print "Test - gettattribute"
return super(Test, self).__getattribute__(name)
def f():
print "executing f()"
return 10
f  = smeth(f)

print Test.f   #displays function obj not unbound method obj!
Test.f()

However, my code does not seem to obey this description in the How-To
Guide to Descriptors:

-
Alternatively, it is more common for a descriptor to be invoked
automatically upon attribute access. For example, obj.d looks up d in
the dictionary of obj. If d defines the method __get__, then
d.__get__(obj) is invoked according to the precedence rules listed
below.***The details of invocation depend on whether obj is an object
or a class***.
...
For objects, the machinery is in object.__getattribute__ which
transforms b.x into type(b).__dict__['x'].__get__(b, type(b)).
...
For classes, the machinery is in type.__getattribute__ which
transforms B.x into B.__dict__['x'].__get__(None, B).
-

When I examine the output from my code, Test.f does not call
Test.__getattribute__(), instead it calls smeth.__get__() directly.
Yet that last sentence from the How-To Guide to Descriptors seems to
say that Test.__getattribute__() should be called first.


I'm using python 2.3.5.

Interesting.  That looks like a functor to me.  Thanks.  I notice that
__get__() overrides __call__().

Will the first character always be a digit?

for i in yourstring.split():
if i[0].isdigit():
yourstring = yourstring.replace(i, '-%s' % (i,))

Or are these hex numbers?

Re: New to Python - Easy way to open a text file

[Max Steel]

Hmm.. maybe it'd help if I explained that I'm playing with edna
http://edna.sourceforge.net/

I'll play with this simple code:
 f = open(r'pathToFile)
 for line in f:
# do something with the line of text such as print it.
 f.close()

and this one from Skip:
f = open(plainfiles.href, "r")
print f.read()

and see if I can make a go of it.. I think it's the template portion that is 
mixing me up.. the template is what's used to create the look of the html on 
the edna server.

Thanks to all who replied so quickly, much appreciated!

Tkinter menu question--how to pass arguments

[Kevin Walzer]

I'm having difficulty structuring a Tkinter menu entry. Here is the 
command in question:

self.finkmenu.add_command(label='Update List of Packages', 
command=self.authorizeCommand(self.scanPackages))

When I start my program, it crashes because it's trying to run the 
command self.authorizeCommand. The reason I'm structuring it in this 
fashion is that this command takes another command as an argument--in 
this case, self.ScanPackages.

The basic structure of the program is that the self.authorizeCommand 
function pops up a dialog box for a password; it then feeds the password 
to the function that it takes as an argument, i.e. self.scanPackages.

I tried setting up the menu entry without the additional parameter, i.e. 
command=self.authorizeCommand, but then when I try to run the command 
from the menu, it complains there are not enough arguments. 
Unsurprising, since self.authorizeCommand takes another function name as 
an argument.

How can I structure the menu item to reflect the correct number of 
arguments without it trying to execute the command?

If self.scanPackages exists as an attribute of self, why do you need to 
pass it in? If your command is just self.authorizeCommand, and that 
method makes use of self.scanPackages when it runs, then it all should 
work without your having to specify it here.
