On which criteria do you fix that?


Anyway, you could use a module myrandom.py:

import random

if use_sys:
     randobj = random.SystemRandom()
else:
     randobj = random.Random()

and then use

from myrandom import randobj as random

and then use random's methods (randrange, random, whatever), no matter 
where they come from.
