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

Question

我对 python 还很陌生。我正在研究一个随机密码生成器。我能够让我的程序生成一个 随机密码。但是它有逗号（,）。我想去掉逗号。

看来我在使用 strip 命令时遇到了错误。下面的程序产生输出：

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

那是因为在你的代码中密码是一个列表，你不能在列表上使用 strip。

试试下面的代码

 #! /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(",")
