now.. another problem..

when i type me = code2()

the error is here..
Traceback (most recent call last):
File "<stdin>", line 1, in <module>

Not surprisingly, because you try to instantiate a module. Which isn't
possible.

What you most probably want is

me = code2.codefly()

May I suggest you move your questions here:

http://mail.python.org/mailman/listinfo/tutor

It seems that you have some very basic misconceptions about python, so that
might be a forum more geared towards your needs.

where ? and what is 'code2' in this context ? Sorry, my crystal ball is

Ok, so it's in the python shell, you imported your module named 'code2',
and tried to call it.

Well... the error message say it all: module objects are not callable
(IOW : they are not functions). If I may ask : what's your background in
programming ?

Your code was/is in code2.py
-----------------

class codefly:
def WaitFreecatz(self, hours):
hours = self.hours
i =1
while i < hours:
print ' i wait for %s hours' %(i)
i = i+1
if i ==hours:
print 'he never comes'

-----------------

The message is pretty clear. Why are you trying to call the module you
just imported? Perhaps you meant to instantiate the class that was
defined there. In that case, the syntax would be:
me = code2.codefly()

To save you some trouble on your next bug, let me point out that your
class does not initialize its instance variable self.hours That's
normally done in the __init__() method. Also, you can interactively see
the objects of an object with the dir() function. So try
dir(code2) dir(code2.codefly) and dir(me)

Sorry to be so blunt, but your main problem is that you don't
know how to ask questions. Fix that, and everything else will
become much easier:

1) Read this: http://catb.org/~esr/faqs/smart-questions.html

2) Read it again.

You could look at the desktop package for something similar:

http://pypi.python.org/pypi/desktop

The desktop.open function supports a few extra workarounds, mostly
because it pre-dates xdg-open.

My class only really needs one attribute, which is a regular expression,
so I thought to save a line or two by subclassing that ;)

You can't get a runtime error there, because nothing instantiates the
class, nor calls its method. Once you add that code, you'll find an
uninitialized instance attribute, plus a couple of logic errors.

So, if you actually have a question, how about stating it completely?
Given a complete code sample, you run it (on what version of what
computer language, on what OS), and you get some error (show complete
traceback). Explain what you tried, to identify the error, and then
state what has you stumped.

And if you don't get a Python error, but get the wrong results, then
state what you expected, and what you got.

wrt/ the code : bad capitalisation on the class name and method name,
access to an inexistant attribute, useless param 'hours' (not used),
failure to use the appropriate iteration construct.

wrt/ your post: failure to post both the full traceback and the minimal
required code to produce this traceback.

Hello everyone,

I'm going nuts with some regex, could someone please show me what I'm
doing wrong?

I have an XMPP msg :

the <parameter> node may be absent or empty (<parameter/>), the <x> node
may be absent. I'd like to grab everything exept the <payload> nod and
create something new using regex, with the XMPP message example above
I'd get this :

for some reason my regex doesn't work correctly :

r"(<message .*?>).*?(<mynode
.*?>).*?(?:(<parameters>.*?</parameters>)|<parameters/>)?.*?(<x .*/>)?"

I group the opening <message> node, the opening <mynode> node and if the
<parameters> node is present and not empty I group it and if the <x>
node is present I group it. For some reason this doesn't work correctly :

>>> import re

Gabriel, trying to debug a long regex in situ can be a nightmare however
the following technique always works for me...

Use the interactive interpreter and see if half the regex works, if it
does your problem is in the second half, if not it's in the first so try
the first half of that and so on an so forth. You'll find the point at
which it goes wrong in a snip.

Non-trivial regexes are always best built up and tested a bit at a time,
the interactive interpreter is great for this.

I'll just add that the "now you have two problems" quip applies here,
especially when there are very good XML parsing libraries for Python
that will keep you from having to reinvent the wheel for every little
change.

See sections 20.5 through 20.13 of the Python Documentation for
several built-in options, and I'm sure there are many community
projects that may fit the bill if none of those happen to.

Personally, I consider regular expressions of any substantial length
and complexity to be bad practice as it inhibits readability and
maintainability. They are also decidedly non-Zen on at least
"Readability counts" and "Sparse is better than dense".

Intchanter
Daniel Fackrell

P.S. I'm not sure how any of these libraries are implemented yet, but
I'd hope they're using a finite state machine tailored to the parsing
task rather than using regexes, but even if they do the latter, having
that abstracted out in a mature library with a clean interface is
still a huge win.

That is going to be a nontrivial exercise. I have control over the pattern, but the texts to be substituted and substituted into will be read from user supplied files. I need to reproduce the exact text the is read from the file.

Maybe what I should do is use re to break the string into two pieces, the part before the pattern to be replaces and the part after it, then splice the replacement text in between them. Seems like doing it the hard way, but it should work.

Thanks,

There is a helper function re.escape() that you can use to sanitize the
substitution:

>>> print re.sub('abc', re.escape(r'a\nb\nc'), '123abcdefg')
123a\nb\ncdefg

I've been given a MAC AIR laptop with OS X 10.6 "Snow Leopard".
On my desktop I dual boot with XP - Ubuntu and have Python on both.
Unfortunately all my Python programs are written on Windows XP and
I heavily rely on WConio for console I/O.
Called Apple tech support. The technician had never heard of Python,
ascertained the MAC AIR does not come preloaded with Python and
did not know if Python 3 would run under OS X 10.6. This was "beyond"
their expertise.
Does anyone have experience with OS X ? Could I use WConio in a
Windows emulator ? I have no experience with MACs and am debating
whether to send this back before opening.
Thanks. Dave WB3DWE

Nice :-)

I was starting to experiment data flow programming with python myself,
although I'm just playing with it..
I find the idea of data flow programming fascinatin, and wonder if it
can be considered a general-purpose program paradigm.

I am trying to execute a windows command based on a shell by mean of
python. I have proven subprocess

test=subprocess.Popen
(['shell_command'],shell=True,stdin=PIPE,stdout=PIPE)

Initally, all seems ok, but, after seconds the python shell is frozen.

Does someone know alternative ways valid for windows OS?

Thanks in advance

josu
