Is Pythons random.randint statistically random?

Question

So I\'m testing an calculating the probabilities of certain dice rolls, for a game. The base case if that rolling one 10sided die.

I did a million samples of this,

Answer 1

I reran the OP's exercise with one billion iterations:

from collections import Counter
import random
n = 1000000000
c = Counter(random.randint(1, 10) for _ in xrange(n))
for i in range(1,11):
    print '%2s  %02.10f%%' % (i, c[i] * 100.0 / n)

Here's the (reformatted) result:

 1     9.9996500000%
 2    10.0011089000%
 3    10.0008568000%
 4    10.0007495000%
 5     9.9999089000%
 6     9.9985344000%
 7     9.9994913000%
 8     9.9997877000%
 9    10.0010818000%
10     9.9988307000%
