txt中的python正则表达式

Question

我有一个txt文件，需要找到最小6位数字，大写和小写字母，数字和标点符号。我的错误是什么？

import re
word_list = []
with open('passwords.txt') as f:
    for line in f.readlines():
        word_list += re.findall(r'^?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{6}', line)

Answer 1

你可以试试：

import re
word_list = []
with open('passwords.txt') as f:
    for line in f.readlines():
        word_list += re.findall(r'[0-9a-zA-Z!@#$%^&*]{6}', line)
