python生成随机复杂可靠的密码

import string
import random

# 标点符号库
punctuation_store = string.punctuation
# 大写字母库
ascii_uppercase_store = string.ascii_uppercase
# 小写字母库
ascii_lowercase_store = string.ascii_lowercase
# 数字字母库
digits_store = string.digits
# 全部库
all_store = punctuation_store + ascii_uppercase_store + ascii_lowercase_store + digits_store
