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

WARNING this answer should be ignored due to critical security issues!

Option #2 seems quite reasonable except you could add a couple of improvements:

''.join(choice(chars) for _ in range(length))          # in py2k use xrange

_ is a conventional "I don't care what is in there" variable. And you don't need list comprehension there, generator expression works just fine for str.join. It is also not clear what "slow" means, if it is the only correct way.
