python: maximum and minimum integer

Scenarios

Sometimes you need to initialize some variables, let denote the largest possible value or a small value as possible.

python2

import sys

max_value = sys.maxint
min_value = -sys.maxint - 1

python3

sys.maxintConstant start deleting from Python 3.0, but the use of sys.maxsize

import sys

max_value = sys.maxsize
min_value = -sys.maxsize - 1

py2 and py3 common

max_value = float('inf')
min_value = float('-inf')
