Examples for string find in Python

Question

I am trying to find some examples but no luck. Does anyone know of some examples on the net? I would like to know what it returns when it can't find, and how to specify from start to end, which I guess is going to be 0, -1.

you can use str.index too:

>>> 'sdfasdf'.index('cc') 
Traceback (most recent call last):
File "<pyshell#144>", line 1, in <module>
'sdfasdf'.index('cc') 
ValueError: substring not found 
>>> 'sdfasdf'.index('df')
