It looks like you are matching something from program output or a log file.

In this case you want to match enough so you have confidence you are matching the right thing, but not so much that if the output changes a little bit your program goes wrong.

Regular expressions work well in this case, eg

>>> import re
>>> mystring = "You have 15 new messages and the size is 32000"
>>> match = re.search(r"(\d+).*?messages.*?size.*?(\d+)", mystring)
>>> if not match: print "log line didn't match"
... 
>>> messages, size = map(int, match.groups())
>>> messages
15
>>> size
32000
