Supposing you call "embedding" inserting a widget in the text via the  
window_create method, why should they? Embedding a window in a Text is  
used to put some arbitrary widget in the middle of the text it contains.  
So the embedded widget has no reason to grow or shrink with the parent  
Text widget: it just moves with the text.

As James said, the  event is your friend. But I'm not sure I

Web File System

[anthony . cutrone]

Hi group,

I have a development with a file system in Python, accessible from a 
graphic web application.

I mustn't use an NTFS or EXT3 system, because those are not adapted 
for my use. Indeed, I would like my system to be able to recover 
files, and get precedent versions. I also want it to index words 
contained in files, to search with these.

Files and folders have to be in an SQL database, mounted in ext3-like 
system. File would be identified by a single ID, and links with names 
should be connected on these IDs.

Somebody have already worked (in Python) about this kind of things ? 
is there a publicly available framework or toolkit ?

thanks

Hi all.
I'd like to test the SpecTix package (GUI generation for TK). I have 
read somewhere that it can generate GUI code for python, but the 
download location (http://starship.python.net/crew/mike/Spectix/) is 
inactive.
Could someone provide a copy of the package or suggest an alternate 
download site?
Latest version seems to be 1.2a3-1.4.
Thank you.

I do not understand extractly what you are asking, but do you know

I would give a look to Content Management Systems such as Zope for

from random import choice
pwdchars = ''.join(chr(c) for c in range(ord('a'),ord('z')+1)+
range(ord('A'),ord('Z')+1)+
 range(ord('0'),ord('9')+1) )

while(True) : print ''.join(choice(pwdchars) for i in range(8))


(Note that you want to use range(8), not range(1,8), since range gives 
you the values [a,b) if two arguments are given, or [0,a) if only one 
is given, and it appears that you want 8-character passwords.)

But really, there's nothing wrong with using import, and reusing known 
good code from the string module is better than reimplementing it in 
new code as I have done (less code === fewer opportunities for bugs).  
rand is not a built-in as it apparently is in Perl, but random is part 
of the core library, so all Python installs will have it available - 
likewise for string.

Make a loop.

> who can write this smaller

I won't write it for you, but I'll tell you how:

Write a function for the whole loop and the password generator and from 
then on it will be a one-liner (as a function call).

 > or without 'import'?

Yes, make sure you do the import inside the function.

If you follow my advice, you will be able to get as many passwords as 
you want with one line (and no spaces, even!):

generate_passwords()

It also reads much clearer than the perl version, don't you think?

By the way, you can also make a script. Call it "genpass", then at the 
command prompt, it will be far less than one line:

 % genpass

Or, if you are using DOS/Windows:

 C:> genpass

A lot of systems don't have a standard command called "g", so then you 
can turn it into *ONE LETTER*!!! That beats the pants off perl!

 % g

Or, of course, for DOS:

 C:> g

Good luck!

interactive prompt in IDLE

[Jan Kanis]

Hello everyone,

I'm trying to change the interactive python prompt. According to the docs  
this is done by changing sys.ps1 and sys.ps2 . That works fine when  
running python interactively from a command line, but when running in IDLE  
the .ps1 and .ps2 don't seem to exist.

I suppose this has something to do with Idle and the python shell in it  
both running in different processes, with the prompts generated by the  
Idle process?

Does anyone know if and how to change the prompts in IDLE's interactive  
python?

Conversion of string to integer

[jupiter]

Hi guys,

I have a problem. I have a list which contains strings and numeric. 
What I want is to compare them in loop, ignore string and create 
another list of numeric values.

I tried int() and decimal() but without success.

eq of problem is

#hs=string.split(hs)
hs =["popopopopop","254.25","pojdjdkjdhhjdccc","25452.25"]

j=0
for o in range(len(hs)):
print hs[o],o
p=Decimal(hs[o])
if p > 200: j+=j
print "-"*5,j
print "*"*25

I could be the best way to solve this ..?

Security note: if you're trying to generate real passwords this way,
you're better off using os.urandom instead of the random module to
generate the random numbers.  The random module's results are supposed
to be statistically uncorrelated (good for stuff like games and

If you really want a hack, here it is:

while 1:print 
''.join(__import__('random').choice(__import__('string').letters+'1234567890') 
for x in xrange(8)),;n=raw_input()

Exactly, Honorable J Klein, (although my reference was a general one, 
you have entered the thread, so I will pick the swiss case) more like 
tributaries to the conquerers ... If you remember that the Japanese 
buy the US govt bonds because their whole country's policy is 
controlled and under the ceiling of the occupiers. The swiss insurance 
companies quietly paid Larry Silverstein $3billion insurance claim 
ONLY after a few months of premium, without raising a single objection

who has flied 100 combat missions, and was running for public office 
is a mad person?? But the point is accurate: Switzerland is not a 
banker but a tributary. You will soon see US twisting the arms of all 
its occupied and conquered races to share the financial loss from 
Bush's foolish policies. That exactly is the UNSTATED methodology.

Still, I would like to go and live in switzerland, if there is a way 
to become a swiss citizen ... like marc rich whom clinton gave 
immunity ... my record is a lot honest than that crook. where do you

HTMLParser's start_tag method never called ?

[ychaouche]

Hi, python experts.


[EMAIL PROTECTED]:~/TEST$ python nettoyageHTML.py
[EMAIL PROTECTED]:~/TEST$


This is the nettoyageHTML.py python script


from HTMLParser import HTMLParser

class ParseurHTML(HTMLParser):
def __init__(self):
HTMLParser.__init__(self)

def start_body(self,attrs):
print "this is my body"

p = ParseurHTML()
p.feed(open("/home/chaouche/TEST/AJAX/testXMLRPC.html","r").read())


this is the testXMLRPC.html html file :








if (typeof netscape != 'undefined' && typeof netscape.security != 
'undefined') {

netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRea
d');
}

var chiffre = 0;
handler = function (self){
if (self.xmlhttp.readyState == 4) {
reponse = self.xmlhttp.responseText;
//dump(reponse); permet d'acceder au dom si ce qu'on a recu est une 
forme de xml.
document.getElementById("txt").innerHTML=reponse;
}
}

function recupDonnees(){
chiffre+=1;
client = new ClientXMLRPC();
client.setUrl("http://10.75.49.100:8081/bonjour/sayHi?
chiffre="+chiffre);
client.executer();
client.handlerEvenement = handler;
}
recupDonnees();





NON




The script should output "this is my body", but nothing is printed. 
Anyone ?

Re: stop script w/o exiting interpreter

May I recommend wrapping your main program in a function definition? Such 
as:

main():
# Bulk of your code (use a macro to indent it faster)

if __name__ == "__main__":
main()

Then you should be able to throw in a "return" at any point and get a 
clean break, without affecting the flow of your program. This should make 
it easier to debug as well, offering a clean entry point from the python 
interactive session, and letting you return a specific value you wish to 
check.

Uh oh.  I was looking at the Python "SSL" code recently, and
noted that OpenSSL initializes the keys with '/dev/urandom' if
available, and otherwise relies on the caller to seed it with
random data and to check that enough randomness has been input.

But the Python glue code for SSL doesn't seem to have the
machinery to seed SSL with randomness.  I suspect that on
platforms without '/dev/urandom', Python's SSL package may
be using the same keys every time.  This needs to be looked
at by a crypto expert.

Can I undecorate a function?

[Matthew Wilson]

The decorator as_string returns the decorated function's value as
string.  In some instances I want to access just the function f,
though, and catch the values before they've been decorated.

Is this possible?

def as_string(f):
def anon(*args, **kwargs):
y = f(*args, **kwargs)
return str(y)
return anon

@as_string
def f(x):
return x * x

It's much simpler not to use the decorator syntax if you also want 
access to the original function.

Simply declare f as a function, then assign decorator(f) to some other name.

This is OK for the node itself, but maybe you should try writing a 
LinkedList class that you use:

class LinkedList(object):
def __init__(self):
self.head = None

def append(self, node):
...

def remove(self, node):
...

>>> ll = LinkedList()
>>> ll.append(Node(3490))

(For extra fun, make it so you can iterate over the linked list and 
call it like this:for n in ll: print n   :-) )

I'd classify this as "not pretty".  Sure, it's more "dynamic" in that 
you don't have a variable to reference every node, but it's way 
cleaner to make an encapsulating LinkedList class, right?

In in Python, references to objects are very much like pointers in C:

>>> foo = Node(3490)  # foo is a reference to a Node instance
>>> bar = foo   # bar points to the same Node instance as foo
>>> foo
<__main__.Node object at 0xb7b362ec>
>>> bar
<__main__.Node object at 0xb7b362ec>

See?  They point to the name Node object.

I agree with you, if your goal is to implement your own list.  Using 
the Python functionality just makes things less clear.

Absolutely.  The "next" pointer thing is the way to go, so you're on 
the right track with that.

When deleting nodes from the list, you don't explicitly delete them; 
you just need to remove all your references to them.  Nodes will be 
garbage collected when there are no more references to them anywhere.

[Boost.Graph] graph.vertices property creates new objects

[George Sakkis]

I've just started toying with the python bindings of BGL and I'm 
puzzled from the following:

>>> from boost.graph import Graph
>>> g = Graph()
>>> v = g.add_vertex()
>>> g.vertices.next() == v
True
>>> g.vertices.next() is v
False

It seems that the vertices iterator creates new vertex objects every 
time instead of iterating over the existing ones. This essentially 
prevents, among other things, storing vertices as keys in a dictionary 
since the hashes of the stored and the new vertex differ although they 
compare equal. Is this really what's happening, and if so, why ?

Use a dictionary?

If you know how large the list eventually will be, and that each 
position is filled, you can also use range(n) to create a list.

What is your actual usecase?

The issue is that I don't know how long the list will eventually be. 
Essentially I'm trying to use a 2D list to hold lines that I will 
eventually print to the screen. Blank elements in the list will be 
printed as spaces. I suppose every time I add an element, I could find 
the difference between the size of the list and the desired index and 
fill in the range between with " " values, however I just wanted to 
see if there was a more natural way in the language.

According to Oleg Kalugin, former head of the KGB's First 
Directorate (overseas espionage), his old employers owned 
someone in just about every important government agency in 
India, from the 1970s until they stopped being able to 
afford paying all those bribes.

Kalugin's book /The_First_Directorate/ is very interesting 
(even if he's a bit cagey in what he says and what he leaves 
unsaid).  Circumlocution didn't help Kalugin, though - he's 
on Putin's hit list anyway.  He can look forward to reading 
by his own light at bedtime if he's not careful from now on.

You can iterate over the list and use the type() function to work out 
what each entry and choose what to do with it.

type() works like so:
###Code###
>>> a = ["test", 1.25, "test2"]
>>> if type(a[2]) == str:
print "a string"


a string
>>>
###End Code###

You could write your own class mimicing a list with your desired 
behaviour, something like:

py>class llist(object):
py>def __init__(self, arg = []):
py>self.__list = arg
py>def __setitem__(self, key, value):
py>length = len(self.__list)
py>if  length < key:
py>for i in range(length, key +1):
py>self.__list.append(None)
py>self.__list[key] = value
py>def __str__(self):
py>return str(self.__list)
py>
py>x = llist()
py>x[10] = 1
py>print x
[None, None, None, None, None, None, None, None, None, None, 1]

for other methods to add to the llist class see http://docs.python.org/

function isinstance can help you to determine the type/class of an

popopopopop

Please don't perpetuate this bad habit!!!  "arg=[]" is evaluated at 
compile time, not runtime, and will give all default-inited llists the 
same underlying list.

The correct idiom is:

def __init__(self, arg = None):
if arg is not None:
self.__list = arg

I avoid using MySQL - SQLite does a better job as a lighweight 
SQL-compliant no-server solution, and PostgreSQL is years ahead of MySQL 
when it comes to serious, rock-solid transactional RDBMS. But I had no 
problem with the MySQLdb package so far. I also tend to favor 
Apache-independant deployment solutions, so while I had some fun with 
mod_python, I failed to clearly understand how broken it is. And I did 
not have to worry about the ssl support in Python so far. FWIW, I had do 
some LDAP stuff with both PHP and Python, and I would certainly not 
advocate PHP's LDAP support.

Executing Javascript, then reading value

[Melih Onvural]

I need to execute some javascript and then read the value as part of a 
program that I am writing. I am currently doing something like this:

import htmllib, urllib, formatter

class myparser(htmllib.HTMLParser):
insave = 0
def start_div(self, attrs):
for i in attrs:
if i[0] == "id" and i[1] == "pr":
self.save_bgn()
self.insave = 1

def end_div(self):
if self.insave == 1:
print self.save_end()
self.insave = 0

parser = myparser(formatter.NullFormatter())

#def getPageRank(self, url):
try:
learn_url = "http://127.0.0.1/research/getPageRank.html?q=http://
www.yahoo.com&"
pr_url = urllib.urlopen(learn_url)
parser.feed(pr_url.read())
except IOError, e:
print e

but the result is the javascript function and not the calculated 
value. Is there anyway to get the javascript to execute first, and 
then return to me the value? thanks in advance,

Melih Onvural

Compiling extension with Visual C++ Toolkit Compiler - MSVCR80.dll

[alexandre_irrthum]

Hi there,

I am trying to install a Python library with a C extension (the 
Polygon library) and I am having a bad time. My Python version is 
Python 2.4.3 - Enthought Edition 1.0.0 (#69, Aug  2 2006, 12:09:59) 
[MSC v.1310 32 bit (Intel)] on Windows XP Pro. I have dutifully 
followed the instructions here:

http://wiki.python.org/moin/Building_Python_with_the_free_MS_C_Toolkit

i.e.,

- Installed Microsoft Visual C++ Toolkit Compiler 2003
- Installed Microsoft Platform SDK for Windows Server 2003 R2
- Installed Microsoft .NET Framework SDK, version 1.1
- setup the path, include and lib environment variables with a .bat 
file, as described in the wiki document

The library seems to build correctly (producing Polygon.py and 
cPolygon.pyd), but when I import it I get the following message from 
python.exe: "This application has failed to start because MSVCR80.dll 
was not found". I thought that this might be due to Python trying to 
link against  the .dll from Microsoft Visual C++ Express 2005, also 
installed on my PC, instead of MSVCR71.dll. So I've removed MS Visual C
++ Express 2005, and any trace of it from my environment variables, 
but that doesn't seem to change anything.

Any help would be greatly appreciated.

Regards,

alex

I would use DBR's suggestion to use a dictionary and only store
actual values. In this example, I'm making a histogram that only
ends up having results for 4,7,8,9,10 but I want the graph to show
the zero occurrences as well, so I just create them on the fly
when printing.

print
print 'tc factor of 2 distribution (* scale = 8)'
print
tchistkeys = tchist.keys()
tchistkeys.sort()
prev_key = 0
for i in tchistkeys:
while prev_key0:
s = s + '.'
print s
prev_key += 1

##tc factor of 2 distribution (* scale = 8)
##
##  0 (  0)
##  1 (  0)
##  2 (  0)
##  3 (  0)

For reverse processing, you need to parse it with an
SGML/XML parser.

Please make a terminology difference between "entity", "entity
reference", and "character reference".

An (external parsed) entity is a named piece of text, such
as the copyright character. An entity reference is a reference
to such a thing, e.g. ©

A character reference is a reference to a character, not to
an entity. xmlcharrefreplace generates character references,
not entity references (let alone generating entities). The
character references in XML and HTML both reference by
Unicode ordinal, so it is "the same".

Not through Python code. In C code, you can look at the

How is this an issue ? Python's lists are not fixed-sized arrays.

Yes. But note that [1,2,3,' ',' ',4]
is not the same thing as [1,2,3,,,4] (which is not valid Python FWIW).

> however I just wanted to 
> see if there was a more natural way in the language.

I'm not sure I get it. Do you mean you're trying to use a list of lists 
as a representation of a 2D matrix (IOW, a bitmap) ? Something like

bpm = [
   ['X',' ',' ',' ','X'],
   [' ','X',' ','X',' '],
   [' ',' ','X',' ',' '],
   [' ','X',' ','X',' '],
   ['X',' ',' ',' ','X'],
]

If so, using dicts can be somewhat simpler and less memory-consuming:

d = {1:1, 2:2, 3:3}
d[10] = 4
for i in range(1, max(d.keys())+1):
   print d.get(i, ' ')

That is, instead of storing useless spaces for "blank cells" and having 
to do math to compute how many of them you have to insert/delete, you 
just place stuff at desired indices, and 'fill in' spaces when printing 
out to screen.

Can you find out where msvcrt.lib comes from? If you manage to copy
the linker command line, I think link.exe has a way of telling you
where it picked up the file. If that won't work, and you find multiple
copies of msvcrt.lib on your disk, you can use dumpbin /all on
each of them to find out which one is right.

But in this anglo-saxon heaven, monica lewinsky owns every president

I think that's the first time I've actually seen someone use a Monty
Python theme for a python example, and I must say, I like it.  However,

i don't know much about bgl, but this is possible since vertices are

that sounds bad, fortunately __hash__ can be overriden so even if id() 
differs hash() can be the same for the same vertex.
if __hash__ is not handled then it's a bug in bgl imho.

SHORT VERSION:
Python File B changes sys.stdout to a file so all 'prints' are written 
to the file.  Python file A launches python file B with os.popen("./B 
2>&^1 >dev/null &").  Python B's output disappears into never-never 
land.

LONG VERSION:
I am working on a site that can kick off large-scale simulations.  It 
will write the output to an html file and a link will be emailed to 
the user.  Also, the site will continue to display "Loading..." if the 
user wants to stick around.

The simulation is legacy, and it basically writes its output to stdout 
(via simple print statements).  In order to avoid changing all these 
prints, I simply change sys.stdout before calling the output 
functions.  That works fine.  The whole thing writes to an html file 
all spiffy-like.

On the cgi end, all I want my (python) cgi script to do is check for 
form errors, make sure the server isn't crushed, run the simulation 
and redirect to a loading page (in detail, I write a constantly 
updating page to the location of the final output file.  When the 
simulation is done, the constantly updating file will be magically 
replaced).  The root problem is that the popen mechanism described 
above is the only way I've found to truly 'Detach' my simulation 
process.  With anything else, Apache (in a *nix environment) sits and 
spins until my simulation is done.  Bah.

Any ideas?

deepcopy alternative?

[none]

I have a very complex data structure which is basically a class object 
containing (sometimes many) other class objects, function references, 
ints, floats, etc.  The man for the copy module states pretty clearly 
that it will not copy methods or functions.  I've looked around for a 
while (prob just using the wrong keywords) and haven't found a good 
solution.  As a workaround I've been using cPickle, loads(dumps(obj)) 
which is incredibly slow (~8 sec for a 1000 elem list).

I believe the only thing stopping me from doing a deepcopy is the 
function references, but I'm not sure.  If so is there any way to 
transform a string into a function reference(w/o eval or exec)?

Example
from copy import deepcopy
a = ClassObj([ClassObj([3.2, 'str', funcRef]), 4, ClassObj[funcRef])
b = deepcopy(a)
TypeError: function() takes at least 2 arguments (0 given)

All I want is a deepcopy of the list.  Any suggestions would be appreciated.

Jack Trades

PS: If the answer to this is in __getstate__() or __setstate__() is 
there some reference to how these should be implemented besides the 
library reference?

select windows

[Siqing Du]

Hi,

Is there is a way to write a program to select and switch between
windows? For instance, if I have three windows: Firefox, Thunderbird,
and emacs, can I run a program to bring up the desired windows, instead
of click on the  windows use mouse.

Thanks,

Du

Call me crazy, but I can't understand what the above code is meant to 
demonstrate.

(1) All of the elements in "hs" are *known* to be of type str. The 
above code never reaches the first elif. The OP's problem appears to 
be to distinguish which elements can be *converted* to a numeric type.

(2) if isinstance(i, some_type) is true, then (usually) some_type(i) 
does exactly nothing that is useful

Awaiting enlightenment ...

Hil to W: Clean up your own mess
Leaving it to next Prez is irresponsible, she tells Iowa crowd

BY MICHAEL McAULIFF
DAILY NEWS WASHINGTON BUREAU

Hillary Clinton addresses crowd at town-hall style meeting yesterday 
in Davenport, Iowa. Her two-day swing through Iowa, where she hit hard 
on issues like Iraq war and health care, was first trip to state with 
earliest caucus since announcing presidential candidacy.
DAVENPORT, Iowa - President Bush should clean up the mess he made in 
Iraq and bring American troops home before he leaves the White House 
in 2009, Sen. Hillary Clinton said yesterday.

Clinton fired her rhetoric-raising broadside at Bush and the Iraq war 
on her first swing through Iowa as a presidential hopeful, painting 
herself as tough, warm and presidential all at the same time.

"The President has said this is going to be left to his successor," 
she said at a rally in Davenport. "I think it's the height of 
irresponsibility, and I really resent it.

"This was his decision to go to war; he went with an ill-conceived 
plan, an incompetently executed strategy, and we should expect him to 
extricate our country from this before he leaves office," the former 
First Lady said.

White House spokesman Rob Saliterman criticized Clinton (D-N.Y.) for 
"a partisan attack that sends the wrong message to our troops and the 
Iraqi people."

One questioner challenged Clinton to explain her vote in late 2002 to 
authorize the war. She said Congress was "misled" at the time by the 
President.

"He took the authority that I and others gave him, and he misused it," 
she said. "And I regret that deeply. And if we had known then what we 
know now, there never would have been a vote, and I never would have 
voted to give this President that authority."

Dawn Trettin, 33, and her son Ramon Briones, 18, who has joined the 
Army, said they liked what they heard from Clinton. Trettin, though, 
teared up when someone in the crowd told her son not to go to Iraq.

"I don't want to just pull out and leave it in chaos," she said, 
though she was waiting to make up her mind on whom to vote for next 
year.

Her son, who said he liked Clinton's depth, was ready to commit after 
hearing her pitch. "I liked her," he said. "I would vote for her."

Clinton is leading her Democratic rivals in national polls, but she is 
not the front-runner in Iowa. If Iowa's first-in-the-nation caucus was 
held now, she would lose to 2004 vice presidential nominee John 
Edwards. She also trails former Iowa Gov. Tom Vilsack and Illinois 
Sen. Barack Obama in state polls.

She completed a two-day swing through the state last night in a bid to 
close the gap and tried to erase the perception among many Iowans that 
she can't win, talking to them in small groups in living rooms and by 
the thousands in large halls.

The reception was strong, and Camp Clinton liked what it saw.

"We are thrilled with the weekend," said Clinton spokesman Howard 
Wolfson.

Clinton also focused on middle-class issues like making college more 
affordable and obtaining universal health care coverage.

She promised to try to at least get universal coverage for kids during 
her next two years in the Senate.

Today, she's picking up the war theme theme again in Texas, attending 
the dedication of Brooke Army Medical Center's $50 million Center for 
the Intrepid. The 60,000-square-foot physical rehabilitation center is 
for veterans injured in the war.

for me deepcopy(lambda:1) does not work in py2.4 but it works in py2.5

Please stop spamming this list with off-topic profanities.  Your
ramblings have nothing to do with programming in Python (this is a
computer-related group by the way) and grow tiresome.  I generally
tolerate occasional off-topic posts because they can be intelligent,
witty, diverting, and sometimes informative and educational.  However
your posts are none of these things.  There are plenty of forums out
there for you to vent your frustrations and express your beliefs and
opinions.  Kindly take your musings elsewhere, particularly when you
have to resort to using profanity to make up for your lack of elegant
expression and inability to argue a point, or even present a point.

Should this become more of a problem, I would vote in favor of moving
this newsgroup to being moderated.  In fact, I'd be in favor of shutting
down the newsgroup entirely and using the members-only mailing list
exclusively, although I know a number of people here would oppose that.
