limits.py

"""
This module is a Python replacement for some of C/C++ limits.h constants.
It's useful for some algorithms where you need to find max or min element
or check if some value exceeds some limits
and you cannot get some existing value as the starting point (because it's unknown at the moment) or it's inconvenient.

P.S. For numbers you should probably use math.inf and -math.inf
