Calling pcre with ctypes

Recently I discovered the re module doesn't support POSIX character classes: Python 2.5.2 (r252:60911, Apr 21 2008, 11:12:42) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import re >>> r = re.compile('[:alnum:]+') >>> prin

Execfile issue

I'm having (what I assume is) a simple problem regarding the way import and execfile interact. I apologize in advance for my naivete. Lets say I have the function: def Func1(): print dir() execfile('testfile') print dir() X and the file #file: testfile X

Multiprecision arithmetic library question.

I already compiled and installed the GNU multiprecision library on Mac OS X, and link to it in C programs. How do I link to the library from Python? I do not want to download and install redundant material. (I am new to Python) -- Michael Press -- http://mail.python.org/mailman/listinfo/python-

How do I create user-defined warnings?

I already know how to make user-defined exceptions, like this one: class MyException(Exception): pass But for a module I'm making, I would like to make a warning (so it just prints the warning to stderr and doesn't crash the program). I have tried this: class MyWarni

One more socket programming question

I'm now experimenting with the SocketServer class. Originally I subclassed the StreamRequestHandler to make my own custom handler, but a result of this seems to be that the client socket closes after it has been used, instead of staying open. Just as a test, I decided to use BaseRequestHandler
