Python预估破译密码所需时间

本文主要是介绍Python预估破译密码所需时间，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

密码长度、组成不同时，破译密码需要的时间也不同
用python判断一下破解该密码需要多长时间

# # 判断破译密码所需要的时间，对着理论表格敲代码就行了。
import re
password = input()
length = len(password)
alpha = 'qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM'
num = '0123456789'
char = '~!@#$%^&*()_+{}|":?><`,./;[]\=-?\''
# # 最开始设置含有字母、数字、字符为False
contain_alpha = False
contain_num = False
contain_char = False

# # local = bool(re.findall(password, alpha))  # # 找到返回True，没找到返回False
# # print(local)

if length < 3 and length > 0:
    print('破译密码需要: 0.001秒')
