How to match a simple stuff in python:



import re

rg = re.compile("delete change (\d+) ")

m = rg.match("l.cpp#21 - delete change 20007 (t")

Then:



>>> m.group(0)

'delete change 20007 '

>>> m.group(1)

'20007'

rg.search() is similar to rg.match(), but only matches things at the beginning of the string i.e. it would match "delete change 20 " but not "foo delete change 20 ".
