Depending on what your passwords are going to be protecting, be aware that the
default generator in the random module is:
"...completely unsuitable for cryptographic purposes."
Instead, create an instance of the 'SystemRandom' class. You also don't need to
create a list of all of your values. A simple string will do. You should also
look into the 'string' module, as it defines 'letters', 'digits' and
'punctuation' characters for you. Thus, your code be something like:
import random
import string
passlen = 10 # How long should it be?
r = random.SystemRandom()
chars = string.letters + string.digits + string.punctuation
passwd = ""
for i in range(passlen):
passwd += r.choice(chars)
print passwd
