[Python-Dev] Ask a question for a script about re.findall Modlue

[Guido van Rossum]

You shouldn't be asking questions about using Python on python-dev -- this
list is for development of Python.

Your problem is easily explained however: the second argument to p.findall()
should be an offset, not a flag set. (You are confusing re.findall() and
p.findall().)
