randint indeed includes both endpoints:
>>> for i in range(10):
... print random.randint(0, 1)
...
1
1
1
1
0
0
1
0
0
0
Its help string agrees:
>>> help(random.randint)
Help on method randint in module random:
randint(self, a, b) method of random.Random instance
Return random integer in range [a, b], including both end points.
