Generate password in python

Question

I\'dl like to generate some alphanumeric passwords in python. Some possible ways are:

import string
from random import sample, choice
chars = string.letters          


        

Answer 1

For the crypto-PRNG folks out there:

def generate_temp_password(length):
    if not isinstance(length, int) or length < 8:
        raise ValueError("temp password must have positive length")

    chars = "ABCDEFGHJKLMNPQRSTUVWXYZ23456789"
    from os import urandom
    return "".join(chars[ord(c) % len(chars)] for c in urandom(length))

Note that for an even distribution, the chars string length ought to be an integral divisor of 128; otherwise, you'll need a different way to choose uniformly from the space.
