print password.strip(",") AttributeError: 'list' object has no attribute 'strip'

Question

I am fairly new to python. I am working on a random password generator. I was able to get my program to generate a random password. However it has commas (,) in it. I would like to strip the commas out.

It looks like I am getting an error with the strip command. The program below produces the output:

AttributeError: 'list' object has no attribute 'strip'

#! /usr/bin/python

import random
import string

def letter_num():
letter = random.choice(string.letters)
number = random.randint(0,9)
letter_number = [letter, number]
random_letnum = random.choice(letter_number)
return random_letnum

#print letter_num(),letter_num(),letter_num(),letter_num(),letter_num(),letter_num,letter_num(),letter_num()

password = [letter_num(),letter_num(),letter_num(),letter_num(),letter_num(),letter_num(),letter_num(),letter_num()]
print password.strip(",")

Answer 1

That is because in your code password is a list and you cannot use strip on list.

Try the below code

 #! /usr/bin/python

import random
import string

def letter_num():
    letter = random.choice(string.letters)
    number = random.randint(0,9)
    letter_number = [letter, number]
    random_letnum = random.choice(letter_number)
    return random_letnum

password = ""
for a in xrange(10):
    password += str(letter_num())

print password.strip(",")
