Operator interface.\n\

This module exports a set of functions implemented in C corresponding\n\
|
|
to the intrinsic operators of Python. For example, operator.add(x, y)\n\
|
|
is equivalent to the expression x+y. The function names are those\n\
|
|
used for special class methods; variants without leading and trailing\n\
|

'__' are also provided for convenience.\n\
