`operator`¶

Operator interface.

This module exports a set of functions implemented in C 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.
