string.split?

I.e. 

Python 1.5.2+ (#12, Nov 19 1999, 15:00:31)  [GCC 2.95.2 19991024 (release)] on linux2
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> import string
>>> string.split("This is a test")
['This', 'is', 'a', 'test']

string.find?

>>> string.find("1122abc33","abc")
4
>>> string.find("1122abc33","f")
-1
