Question

String example: ‘file_name.c: 120’ or ‘file_name.m: 312’
Target: find exactly ‘.c:’ or ‘.m:’ using regular expression.

Since it’s confusing issue, I would to get a good tutorial for regular expression if someone knows.

Ron.

Answer 1

import re
string = 'file_name.c: 120'
find = re.findall("(\.[cm])*", string)
find = filter(None, find)
print find

I prefer using findall as I am guessing you may be looking for more than one example.
