I have ran a quick test and the distribution is the same, hitting the same
low and high values:
```
def test_randoms(bits, M, epsilon = 0.05):
bit_d = collections.defaultdict(lambda: 0)
normal_d = collections.defaultdict(lambda: 0)
for _ in range(M):
bit_d[random.getrandbits(bits)] += 1
normal_d[random.randint(0, (1 << bits) - 1)] += 1
for key in bit_d:
div = bit_d[key] / normal_d[key]
if not 1 - epsilon < div < 1 + epsilon:
print(bit_d[key], normal_d[key], key, div)
return False
return True
test_randoms(8, 10 * 10**6)
```
Returns True
