- Operator interface.\n\
- \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\
