Using an operator to add in Python

Question

Consider:

operator.add(a, b)

I\'m having trouble understanding what this does. An operator is something like +-*/, so what doe

Answer 1

As operator.add is a function and you can pass argument to it, it's for the situations where you can not use statements like a+d, like the map or itertools.imap functions. For better understanding, see the following example:

>>> import operator
>>> from itertools import imap
>>> list(imap(operator.add,[1,3],[5,5]))
