Is there any python lib for calling CVS api?

[ironpythonster]

  Hi everyone, this should be a quick question.  I'm writing some
scripts
to take some file and move them into a CVS repository, but it's pretty
slow, because it uses system calls to execute the CVS commands.

 Has anyone ever made a python to CVS interface library that I could
use?
Some one sugestion me use the cvsgui lib,but it look like that the lib
could
not use fro Python2.4.I've been trying to google around for something,
but predictably I get
a zillion sourceforge repository hits, and it isn't really helping.  So

anyway, if anyone knows of a useful module, I'd love to hear about it.
Thanks!

Being "old school" or "modern" is not an argument in itself. How do the  
so-called "modern" layout managers help you do the thing you want to do?

And the fact that you could find no mention of something does not mean  
that it doesn't exist. It may just be a documentation problem.

The "Packer" is very rarely used in Tkinter applications when the layout  
becomes complicated. Almost all applications I saw use the "grid" layout  
manager, except for very simple things (like buttons in a row or column,  
where the "pack" layout manager is just enough).

Even though that's a great book I don't recomend it for non
programmers I think this http://docs.python.org/tut/ is a better way
to start

also I'll suggest you start learning other programming languaje before
python or else this will be the only one you will code :)

Problem with XML-RPC not mounted in /

[Almad]

Hi,

I'm trying to build XML-RPC service, both server and client library.

My server is CherryPy with XML-RPC filter. I have here method
registration_ip. When it's in, say http://ws.rpgplanet.nerv/,
everything is OK, but when I move it in http://ws.rpgplanet.nerv/main/,
this behaviour occur:

 srv = ServerProxy('http://ws.rpgplanet.nerv/main/')
 print srv.register_ip("guest")

raises 404, as according to log, library is trying to access /main/
instead of /main/register_ip

 srv = ServerProxy('http://ws.rpgplanet.nerv/')
 print srv.main.register_ip("guest")

raises 500, as client is correctly hitting /main/register_ip, but NOT
sending "guest" argument.

I'm probably missing something obvious, so where should problem be? Is
it not possible for XML-RPC to live not in / ?

Thank You for advices,

Almad

The first question then is: do you really need a middleware ? Most
RDBMSs are already full-blown server applications - with support for
authentification, permissions, triggers and stored procedures - that can
be accessed by client programs in almost any language.

Now if you effectively want/need a web service, it seems that the
canonical solutions are XMLRPC and SOAP. But if you already use a RDBMS,
 this web service should IMHO mostly be designed as an higher-level
interface to the RDBMS, not as a full-blown app managing domain/business
rules (which is the job of the RDBMS). IOW, it should be still possible
for applications to directly interact with the RDBMS.

There are XMLRPC packages for most languages, that knows how to do the
native data structure <-> XMLRPC translation. Python has both client and
server packages in the standard lib.

As the name implies, W(eb) S(ervice) D(escription) L(anguage) is meant
to describe a given web service - and says nothing about implementation.

The error is a bit misleading, since in Python 2.5 all exceptions are new-style,
but new exception classes must be derived from an existing one.
Classic classes, their instances and strings are only allowed for backwards 
compatibility.

On the other hand...

>>> import exceptions
>>> class E(exceptions.Exception):
... pass
... 
>>> raise E
Traceback (most recent call last):
  File "", line 1, in ?
__main__.E

This also has the advantage to let it explicit in the code that E is an

Assuming you don't care what order the strings are in:

r = {'a':('ASLIB','Aslib'),'j':('JDOC','jdoc')}
result = sum(r.values(), ())

If you do care about the order:

r = {'a':('ASLIB','Aslib'),'j':('JDOC','jdoc')}
keys = r.keys()
keys.sort()
result = []
for key in keys:
result.extend(r[key])
result = tuple(result)

I thought exceptions were converted to new-style classes for Py2.5 
(http://docs.python.org/whatsnew/pep-352.html).  I've not upgraded yet, so 
cannot easily test this - under what version of Python was your posted code 
run?

How about a connection broker?

Simple example:

#
connections = {}

def Register( obj ):
try:
connections[obj.name]['obj'] = obj
except KeyError:
connections[obj.name] = { 'obj' : obj, 'connected_to' : [] }

def ConnectTo( objname, obj ):
try:
connections[objname]['connected_to'].append( obj )
except KeyError:
connections[objname] = { 'obj' : None, 'connected_to' :
[obj] }

class ConnectionObject:
def __str__(self):
return self.name

class A(ConnectionObject):
def __init__(self):
self.name = 'A'
Register( self )
ConnectTo( 'B', self )


class B(ConnectionObject):
def __init__(self):
self.name = 'B'
Register( self )
ConnectTo( 'A', self )
ConnectTo( 'C', self )


class C(ConnectionObject):
def __init__(self):
self.name = 'C'
Register( self )
ConnectTo( 'A', self )


a = A()
b = B()
c = C()


for (key, val) in connections.iteritems():
print 'object: %s (%s)' % ( key, val['obj'] )
str_vals = []
for obj in val['connected_to']:
str_vals.append( str( obj ) )
print '\tconnections from:', str_vals

#
Output:

object: A (A)
connections from: ['B', 'C']
object: C (C)
connections from: ['B']
object: B (B)
connections from: ['A']
object: D (None)
connections from: ['C']

That's the most complicated do-nothing function I've ever seen. Here is a
shorter version:

def shortf(*args):
return args


>>> f('foo', 'bar')
('foo', 'bar')
>>> shortf('foo', 'bar')
('foo', 'bar')

>>> f(1,2,3,4)
(1, 2, 3, 4)
>>> shortf(1,2,3,4)
(1, 2, 3, 4)

>>> f({}, None, 1, -1.2, "hello world")
({}, None, 1, -1.2, 'hello world')
>>> shortf({}, None, 1, -1.2, "hello world")
({}, None, 1, -1.2, 'hello world')

Actually, they aren't *quite* identical: your function rips lists apart,
which is probably not a good idea.

>>> f("foo", [1,2,3], None) # three arguments turns into five
('foo', 1, 2, 3, None)
>>> shortf("foo", [1,2,3], None) # three arguments stays three
('foo', [1, 2, 3], None)



I still don't understand why you are doing this. Can we have an example of
why you think you need to do this?

You might get some ideas from ViewVC if you're accessing the repository
directly:

http://www.viewvc.org/

There may be scripts out there which import data from various other
revision control systems into CVS, although the focus these days seems
to be on *exporting* data from CVS and putting it into things like
Subversion, Bazaar, Mercurial and so on, but I believe the scripts for
the latter two are Python programs and may also provide some
inspiration.

Pyparsing comes with an example that parses strings representing lists. 
Here's that example, converted to parsing only tuples of numbers.  Note that 
this does not presume that tuples are only pairs, but can be any number of 
numeric values, nested to any depth, and with arbitrary whitespace, etc. 
This grammar also includes converters by type, so that ints come out as 
ints, and floats as floats.  (This grammar doesn't handle empty tuples, but 
it does handle tuples that include an extra ',' after the last tuple 
element.)

-- Paul
Download pyparsing at http://sourceforge.net/projects/pyparsing/ .


from pyparsing import *

integer = (Word(nums)|Word('-+',nums)).setName("integer")
real = Combine(integer + "." + Optional(Word(nums))).setName("real")
tupleStr = Forward().setName("tuple")
tupleItem = real | integer | tupleStr
tupleStr << ( Suppress("(") + delimitedList(tupleItem) +
   Optional(Suppress(",")) + Suppress(")") )

# add parse actions to do conversion during parsing
integer.setParseAction( lambda toks: int(toks[0]) )
real.setParseAction( lambda toks: float(toks[0]) )
tupleStr.setParseAction( lambda toks: tuple(toks) )

s = '((1,2), (3,4), (-5,9.2),)'
print tupleStr.parseString(s)[0]

Gives:

Check out the Ruby project IFMapper for a mature project that
might accomplish your goal.  You can write a new back-end for it
to produce MUD code (so you can design your maps graphically), or
you can write a new front-end to interpret MUD code (so you can
make IF-Mapper draw maps for you game in progress).

Dear Kaushal,

I was going to recommend exactly that one. That is a very nice book,
clearly written, not patronizing (some begginers books seem to fall
easily into the patronizing mode), and covers a lot of ground.

I think dive into python is a great book, but not the best choice if
you have no programming experience. I also think that the tutorial by
Guido van Rossum is not the best place to start if you have no
programming experience.

You can also go to:

http://www.python.org/doc/


and, in particular,

http://wiki.python.org/moin/BeginnersGuide/NonProgrammers.



If you are looking for a "book I'll pay money for", I'd recommend
"Core Python Programming", by Chun. It's a thick book, which will keep
you busy for a while, and assumes some programming experience. It may
be a good place to go _after_ you've gone through "How to think like a
computer scientist" and, probably, have looked at some other material.

Good luck,

R.

Sorry, I think everyone misunderstood what my problem is. Which is not
very strange since I see now that I didn't explain it very well.

In the code below, I have created a simple Room class. It has up to
four edges; north, east, west and south. The Room class also has the
method get_projection() which recursively traverses through all
reachable rooms in the graphs and gives them x,y coordinates and
returns a dict containing x,y-coordinates and rooms. The function
project_dict() simply plots the dict on stdout.

The main() function demonstrates how a map consisting of nine rooms
should be plotted. All well so far. But if there had been an east-west
edge from G to I, then that edge would have overlapped C:s position.
That would have been wrong and I want the algorithm in
get_projection() to detect such overlaps and automatically fix them.
In this case, the fix would have been to add 2 to G and I:s
y-coordinate. Then the east-west edge from G to I wouldn't overlap any
room.

So I wonder if there is any algorithm that can do what I'm asking for?

Yesterday I tested something like this and got a syntax error. So I got

If i redefine the function g the difference comes visible:

  >>> def g(*arg):
... if with_flattern: arg=flattern(arg)
... return arg

 >>> with_flattern=False
 >>> f('foo', 'bar')
(('foo', 'bar'),)
 >>> with_flattern=True
 >>> f('foo', 'bar')

If you read the whole chain you find out what we were talking of.

AFAIK there is no such thing as a CVS-library. Which was one of the

It depends - it is complicated and very sophisticated and generally
considered a hard, even unsolvable problem. However, a good general
solution is written in the graphviz toolkit. Which is the reason I
suggested it.

But there is no cookbook-algorithm that will produce perfect MUD-maps. For
such a beast, you have to cough up one on your own, with things like
constraint solvers and the like. Certainly over _my_ head, at least without
deep studies of planar graph representation problems.

Use mingw32. It should work fine for most extensions.

that'd be another fat database to blow up the python core(s).

I just wonder why locale.setlocale(locale.LC_ALL,"de_DE") doesn't accept the 
name, which 
>>> locale.getlocale() / getdefaultlocale()
('de_DE', 'cp1252') 
already deliver ?

but only this works

'German_Germany.1252'


But 'German_Germany.1252' you cannot get/guess from any locale.get function

Yes, they were. Still, you can't raise instance of arbitrary new-style classes
as exceptions, and you will never be able to. In Py3k, only instances of
"BaseException" subclasses will be raisable.

I've had programs handling dicts with 1.7million items and it isn't
a great problem, providing you're careful not to duplicate data.
Creating a copy of keys() in a separate list, for example, will
inflate memory usage noticably.

Unless you're on a 64bit OS, that's irrelevant. You'll hit the 2G
per-process limit before you start putting a strain on real memory.

SPE does error syntax checking which works fine for normal sized python
files. With these settings you can speed up SPE for larger projects:
1. Edit>Preferences>Editor: Check realtime with "none" (default value:
compiler)
2. Edit>Preferences>Editor: Update sidebar "when clicked"

You can first try step 1, if you want SPE faster, use step 2 as well.

I don't know if this is the problem or not (knowing neither Qt nor
Twisted), but creWin() creates a window (or two) then throws it
(them?) away on returning to main() (I assume you've chopped
off the bit where main() is actually called). So it's not too
surprising your window doesn't show: by the time you get to
running anything, you don't have a window object to show. (Unless
a Qt application object is a discoverable global and windows
inject a reference to themselves into it.)

[jim-on-linux]

Kath,
You can use this class to pass values around 
without concern for conflicts since it has no 
values of its own.


class Kvariable:
  def setVariable(self, variable):
  self.output = variable

  def showVariable(self):
  print self.output 
  
x = Kvariable()
y = Kvariable()

x.setVariable("James_01")
y.setVariable("Kath_01")

x.showVariable()
y.showVariable()


x.setVariable('3.14159')
y.setVariable("python.org")

x.showVariable()
y.showVariable()

Do you mean the example from the PyQt4 distribution? That uses a port
of an old syntax highlighting example from Qt 4.0. Someone needs to
"port" the C++ example from Qt 4.2 to PyQt4.

The example itself doesn't actually use QScintilla2 - there used to
be a demo from Qt that was converted to use QScintilla. Maybe that's
been ported to PyQt as well.

shutil: permission denied errors on windows

[Antoine De Groote]

Google tells quite some things about it, but none of them are satisfactory.

I'm on Windows, and shutil operations (e.g. move, copy) throw [Errno 13] 
Permission denied all the time, for the source files. It seems that this 
is the case for all my files. But what I don't understand is that 
yesterday it still worked. I didn't change anything on my system though 
(at least not that I am aware of). I restarted the computer several 
times to see if that helped, but it didn't. Also I can't find a process 
that would be using the files...

Has anybody experienced this problem before, or have a solution?

Kind regards,
antoine

Here's the code that throws the errors

[...]
for l in files:
 from_file = os.path.join(dir, l)
 to_file = from_file.replace(tree_top, backup_dir)
 try:
 if not os.path.exists(to_file):

It seems to me that your analysis is correct. The first example
works as expected because MainWindow is still in scope when
the reactor is run.

def main():
 app = QtGui.QApplication(sys.argv)
 qt4reactor.install(app)
 MainWindow = QtGui.QMainWindow()
 win = Window(MainWindow)
 MainWindow.show()
 from twisted.internet import reactor
 reactor.run()

However, in the second example, MainWindow is created as a local
variable inside creWin() and is deleted when that function returns.

def creWin():
 MainWindow = QtGui.QMainWindow()
 win = Window(MainWindow)
 MainWindow.show()
 def main():
 app = creApp()
 creWin()
 from twisted.internet import reactor
 reactor.run()

By the time the reactor runs, there's no window (open or otherwise)
so the application will never exit the Qt event loop (or whatever
actually runs when Twisted is involved).

> (Unless a Qt application object is a discoverable global and

Well, you can access the application's instance, once it's been set
up, via the qApp global variable in the PyQt4.QtGui module. However,
you can't take advantage of Qt's parent-based object ownership
mechanism to get round this issue with local variables because
widgets need to be given QWidget parents, and QApplication is not a
QWidget subclass.

The original poster should either use a global MainWindow variable or
encapsulate the functions in a class.

Yes, from a easy of use standpoint, I agree that PythonCard is very

Unfortunately there isn't more "activities" as one would like to see.

On the other hand, that's typical of open-source projects.  We can
always roll up our sleeves and do it ourselves.

At least the multicolumn control isn't particularly complex, should be
able to figure out from the source code how to sort.  I believe I did

You're probably using a package which is not supported under Python 2.3.
The collections module is new with 2.4.  Try upgrading to 2.4 or 2.5.

If you don't have mingw32, either, you can't build the extension module.
You need to get a supported compiler. If you don't have one, find

Just something like:

class foo:
self.__init__(self, parent):
self.parent=parent

class bar:
self.__init__(self, parent):
self.parent=parent
self.foo=foo(self)


class myclass:
self.__init__(self, parent):
self.parent=parent
self.bar=bar(self)

Now in foo I can reference things from myclass easily
self.parent.parent.  Or setattr(self.parent.parent, value).

Hope this helps.

Re: adding python scripting to my application

[Jerry]

I am not a Python guru by any means, but I believe that when an
application says that you can "script" their application with Python,
it means that you can actually write Python code to interact with the
application.  Embedding may be the same thing.  Extending (as I read
it) involves writing portions of your program in Python and have do the
logic portions.

If you would like to allow users to write small scripts that interact
with your program and control it (a la VBScript or AppleScript), then I
believe embedding Python in your program is what you want.

If you would like Python to run various parts of your program in order
to make some portions easier to write/manage/whatever, then you want to
"extend" your program using Python.

The key difference being that you aren't providing a way for someone
else to interact with your program using Python if you are extending.

Again, I am not a guru and a read through the docs on python.org would
probably be the best place to get sound technical advice on these
subjects.

Suppose you did actually want to do this you have chosen about the worst 
possible way: the use of global variables to condition function 
execution is a sure way to get into trouble. Consider if somebody else 
want to use your function: they also have to set a global in their 
program to avoid your function raising an exception.

Fortunately Python has just the thing to make such horrors unnecessary: 
the default argument value. Try something like this (untested):

def g(flattening=True, *arg):
 if flattening:
arg = flatten(arg)
 return arg

Obviously you could use either True or False for the default value. In 
the case above the function flattens by default. You could also, if you 
wished, have f() take the flattening argument, and always pass it to g().

Nothing very sophisticated here, just something to help you flex your 
growing Python and programming muscles.

Unicode/ascii encoding nightmare

[Thomas W]

I'm getting really annoyed with python in regards to
unicode/ascii-encoding problems.

The string below is the encoding of the norwegian word "fødselsdag".

>>> s = 'f\xc3\x83\xc2\xb8dselsdag'

I stored the string as "fødselsdag" but somewhere in my code it got
translated into the mess above and I cannot get the original string
back. It cannot be printed in the console or written a plain text-file.
I've tried to convert it using

>>> s.encode('iso-8859-1')
Traceback (most recent call last):
  File "", line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1:
ordinal not in range(128)

>>> s.encode('utf-8')
Traceback (most recent call last):
  File "", line 1, in ?
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 1:
ordinal not in range(128)

And nothing helps. I cannot remember hacing these problems in earlier
versions of python and it's really annoying, even if it's my own fault
somehow, handling of normal characters like this shouldn't cause this
much hassle. Searching google for "codec can't decode byte" and
UnicodeDecodeError etc. produces a bunch of hits so it's obvious I'm
not alone.

Any hints?

In future please don't quote the whole of a digest just to ask a simple

helps if you can give a subject line that indicates what you are asking 
about.

Python has getch() in Windows only, there is no getchar(). If you want 
your program to be portable to Linux/Unix as well then getch() won't do. 
I have seen a portable recipe, but my google-fu is low today so I'll 
have to let someone else point that out if you need it.

However, if the Enter key will do then just try inserting

raw_input("Hit Enter to continue: ")

That'll work on any platform.

I'm not sure either, but I though Extending was making the C/C++ Code

I'm not sure which encoding method you used to get the string above.
Here's the result of my playing with the string in IDLE:

>>> u1 = u'fødselsdag'
>>> u1
u'f\xf8dselsdag'
>>> s1 = u1.encode('utf-8')
>>> s1
'f\xc3\xb8dselsdag'
>>> u2 = s1.decode('utf-8')
>>> u2
u'f\xf8dselsdag'
>>> print u2
fødselsdag

No. The default encoding (the return value of sys.getdefaultencoding()) should
alway be 'ascii'. Otherwise, programs written on one machine will not run on
other machines.

It is documented that those functions return cross platform RFC 1766
language code. This code sometimes won't be compatible with OS specific
locale name. Cross platform code can useful if you want to create your
own locale database for example cross platform language packs.

Right now we have:

setlocale(category) -- get(it's not a typo) OS locale name
getlocale(category) -- get cross platform locale name
setlocale(category,'') -- enable default locale, return OS locale name
getdefaultlocale()  -- get cross platform locale name

I agree it's very confusing API, especially setlocale acting like
getter, but that's what we have. Improvement is welcome.

You would want .decode() (which converts a byte string into a Unicode string),
not .encode() (which converts a Unicode string into a byte string). You get
UnicodeDecodeErrors even though you are trying to .encode() because whenever
Python is expecting a Unicode string but gets a byte string, it tries to decode
the byte string as 7-bit ASCII. If that fails, then it raises a 
UnicodeDecodeError.

However, I don't know of an encoding that takes u"fødselsdag" to
'f\xc3\x83\xc2\xb8dselsdag'.

It is not set when you build but is instead set in sitecustomize.py.
But changing it is typically inadvisable in that any programs you write
will not port to other people's machines.

There is no such thing as "*the* encoding" of any given string.

Somewhere in your code??? Can't you track through your code to see
where it is being changed? Failing that, can't you show us your code so
that we can help you?

I have guessed *what* you got, but *how* you got it boggles the mind:

The effect is the same as (decode from latin1 to Unicode, encode as
utf8) *TWICE*. That's how you change one byte in the original to *FOUR*
bytes in the "mess":

| >>> orig = 'f\xf8dselsdag'
| >>> orig.decode('latin1').encode('utf8')
| 'f\xc3\xb8dselsdag'

orig.decode('latin1').encode('utf8').decode('latin1').encode('utf8')

Incorrect. *Any* string can be printed on the console or written to a
file. What you mean is that when you look at the output, it is not what
you want.

encode is an attribute of unicode objects. If applied to a str object,
the str object is converted to unicode first using the default codec
(typically ascii).

s.encode('iso-8859-1') is effectively
s.decode('ascii').encode('iso-8859-1'), and s.decode('ascii') fails for
the (obvious(?)) reason given.

1. Read the Unicode howto: http://www.amk.ca/python/howto/unicode
2. Read the Python documentation on .decode() and .encode() carefully.
3. Show us your code so that we can help you avoid the double
conversion to utf8. Tell us what IDE you are using.
4. Tell us what you are trying to achieve. Note that if all you are
trying to do is read and write text in Norwegian (or any other language
that's representable in iso-8859-1 aka latin1), then you don't have to
do anything special at all in your code-- this is the good old "legacy"
way of doing things universally in vogue before Unicode was invented!

There isn't one.

C3 and C2 hint at UTF-8.
The fact that C3 and C2 are both present, plus the fact that one
non-ASCII byte has morphoploded into 4 bytes indicate a double whammy.

Indeed...

'f\xc3\x83\xc2\xb8dselsdag'

Note that "encode" on a string object is often an indication for an error.
The encoding direction (for "normal" encodings, not special things like
the "zlib" codec) is as follows:

encode: from Unicode
decode: to Unicode

(the encode method of strings first DEcodes the string with the default
encoding, which is normally ascii, then ENcodes it with the given encoding)

 s.encode('utf-8')

Unicode causes many problems if not used properly. If you want to use Unicode
strings, use them everywhere in your Python application, decode input as early
as possible, and encode output only before writing it to a file or another
program.

Ok, so I did

./configure --prefix=/Users/tbrannon/Documents/Python/Swarm/Python-2.5

but during make install I get this:

I believe you're missing the parens around your VALUES to insert. Also,
you need 1 placeholder per argument inserted, not just one for the
entire argument list. Try:

self.connection.execute("INSERT INTO Personal (firstName, lastName)
VALUES (?, ?)", t)

assigning values in __init__

[John Salerno]

Let's say I'm making a game and I have this base class:

class Character(object):

 def __init__(self, name, stats):
 self.name = name
 self.strength = stats[0]
 self.dexterity = stats[1]
 self.intelligence = stats[2]
 self.luck = stats[3]

Is this a good way to assign the values to the different attributes? 
Should 'stats' be a list/tuple (like this), or should I do *stats instead?

I'm trying to think ahead to when I might want to add new attributes, 
and I want to make sure this doesn't get crazy with individual 
parameters instead of just the one list.

Or maybe there's some way to loop through two lists (the stats and the 
attributes) and assign them that way? I was thinking of a nested for 
statement but that didn't seem to work.

Not really.  Indention in python conveys blocks so there is no way

Sounds like what you should be doing is something like keyword arguments
instead.

class Character(object):
def __init__(self, name, **kwargs):
self.name=name
for key, value in kwargs.items():
setattr(self, key, value)


z=Character('name', strength=10, dexterity=5, intelligence=3, luck=0)

Now you can easily introduce new keyword arguments.

How about:

class Character(object):

def __init__(self, name, **kwargs):
self.name = name
self.__dict__.update(kwargs)

c = Character( "Plato", strength=10, luck=12)

print getattr(c, "strength")
print getattr(c, "luck")

If you have no programming experience at all, I highly recomend "Non

This is how I got my feet wet with Python, and it's very easy to

I also recomend "A Byte of Python" by Swaroop:

nothing.I have been looking around more but the informations i find on
that topic seems so clunky and out dated(2004-2003) that i really don't
think i should wast my time any further without asking around if i'm
going the right direction.Because i have the feeling Python/Ldap/win32
shouldn't be such a problem to use...And if it isn't then...Python is
not the language i need to accomplish that task.

Re: Unicode/ascii encoding nightmare

[Thomas W]

Ok, I've cleaned up my code abit and it seems as if I've
encoded/decoded myself into a corner ;-). My understanding of unicode
has room for improvement, that's for sure. I got some pointers and
initial code-cleanup seem to have removed some of the strange results I
got, which several of you also pointed out.

Anyway, thanks for all your replies. I think I can get this thing up
and running with a bit more code tinkering. And I'll read up on some
unicode-docs as well. :-) Thanks again.

Thomas

I strongly suggest that you read the docs *FIRST*, and don't "tinker"
at all.

HTH,

Thank you everybody.
As it is possible that the tuples will not always be the same word in 
variant cases
result = sum(r.values(), ())
  will do fine and is as simple as I suspected the answer would be.

Indeed yourself. Have you ever considered reading posts in
chronological order, or reading all posts in a thread? It might help
you avoid writing posts with non-zero information content.

Use raw_input() and press ENTER.

Best if you follow that suggestion...

ctypes, python 2.5, WinFunctionType and _as_parameter_

[gerard5609]

Hello,

how to get at the function address of a WinFunctionType ctypes object ?
With ctypes 1.0, I used just myfunc._as_parameter_ and all was well.
With ctypes 1.0.1, that ships with python 2.5, WinFunctionType has no
longer an _as_parameter_ attribute

Where in the ChangeLog and the documentation is explained how to deal
with this change ?

Thanks in advance,

Gerard
