Python: lists .remove(item) but not .find(item) or similar?

This question already has an answer here:

Finding the index of an item given a list containing it in Python 23 answers

Interesting that it's not list.find , but list.index :

>>> l = ['a', 'b', 'c']
>>> l.index('c')
2

To test for membership:

>>> 'b' in l
True

Which is equivalent to (and should be used instead of):

>>> l.__contains__('b')
True
