presumably randint is doing something different to get its values.
The docs [https://docs.python.org/3/library/random.html#random.randrange]
for randrange have this note:
Changed in version 3.2: randrange() is more sophisticated about producing
equally distributed values. Formerly

Is there a way to get the same sequences of random numbers in python 2.7 and
python >= 3.3?
I notice that this simple script produces different values in python 2.7 and
>=3.3
C:\code\hg-repos\reportlab>cat s.py
import sys, random
print(sys.version)
random.seed(103)
for i in range(5):
print
