Operator Interface
This module exports a set of functions corresponding to the intrinsic
operators of Python. For example, operator.add(x, y) is equivalent
to the expression x+y. The function names are those used for special
methods; variants without leading and trailing '__' are also provided
for convenience.
This is the pure Python implementation of the module.

Return an estimate of the number of items in obj.
This is useful for presizing containers when building from an iterable.
If the object supports len(), the result will be exact. Otherwise, it may
over- or under-estimate by an arbitrary amount. The result will be an
integer >= 0.

Return a callable object that fetches the given attribute(s) from its operand.
After f = attrgetter('name'), the call f(r) returns r.name.
After g = attrgetter('name', 'date'), the call g(r) returns (r.name, r.date).
After h = attrgetter('name.first', 'name.last'), the call h(r) returns
(r.name.first, r.name.last).
