This is a very generic observation as I don't have a lot of specifics
with me right now. I have noticed over the past two years that the
python "re" module is somewhat unreliable. At the suggestion of
someone quite some time ago, I started to use the deprecated "pre"
module. "import pre as re". All my problems went away.
So here I am two years later, writing another script and I had
forgotten about "pre" and wallah
$ python proc.py
Traceback (most recent call last):
File "proc.py", line 39, in ?
c = collect("nohup.out")
File "proc.py", line 20, in collect
m = p.search(cont)
RuntimeError: maximum recursion limit exceeded
As soon as I switched "import re" to "import pre as re" my program
worked as expected. In the words of Jerry Sienfeld, what's up with
that?

What do you mean with unreliable?
Can you show an example where re does not work as expected?

Try again with Python 2.4. The re module is now non-recursive
( http://www.python.org/2.4/highlights.html), so you shouldn't get any
"maximum recursion limit exceeded" errors.

Like I said, I don't have a lot of specifics. This is more of an over
time experience.
I do know that any problem I had with "re" was always resolved by
"pre". Maybe they all had to do with recursion though.
Thanks for the heads up on python2.4. Now all I have to do is get our
admins to install... sigh
