Looking at my own code I use find() in two cases
1) in an "if" clause where "in" or startswith() would be appropriate
This code was written when I started with python and is closer to
C++ or perl or was a literal translation of a snippet of C++ or perl
2) where try/except around index() would work just fine and partition
would be even better. eg/
try:
parts.append(text[text.index('himom')])
except ValueError: pass
This is 50 uses of find/rfind in 70 KLOCs of python. Considering I would
be better off not using find() in the places I do use it I would be happy
to see it go.
