I need to get a random integer. At first I tried it with:
from secrets import randbelow
index = randbelow(len(to_try))
This works perfectly, but it took some time. So I thought I try:
from random import SystemRandom
index = SystemRandom().randint(0, len(to_try) - 1)
A first indication is that the second version would take about two
times as much time as the first. Is there a reason for this, or should
this not be happening?
