Most of the operator module is functional versions of what can be done
elsewhere with operators. They're not generally needed unless you
specifically need a function, such as for a map() call:

>>> a=[1,2,3,4,5]
>>> b=[50,40,30,20,10]
>>> list(map(operator.add,a,b))
[51, 42, 33, 24, 15]

(The list() call is unnecessary in Python 2, but means this will also
work in Python 3.)
