These are cryptographically secure #PRNGs. Using random.choice instead of random.SystemRandom().choice in an application that requires a secure PRNG could be potentially devastating, and given the popularity of this question, I bet that mistake has been made many times already. ''.join(random.SystemRandom().choice(string.ascii_uppercase + string.digits) for _ in range(N))
