Question

我试图制作一个基本程序来检查密码是否符合某些标准。这不会返回任何错误，但会验证密码＆＃39;消息是否有特殊字符。欢迎任何想法！

import re
begin = str(input("Would you like to check your password strength?"))
while begin.lower() == "yes" or begin.lower() == "y":
    password = str(input("Please enter your password"))
    if len(password)<8:
        print ("Your password needs to be at least 8 characters long")
    elif password.isupper() or password.islower():
        print ("Please and include at least one upper and one lower case letter in your password")
    elif password.isnumeric() or password.isalpha():
        print ("Your password should not be numbers only or letters only but should include a mixture of both")
    elif re.match("£$%^&*()",password) == True:
        print ("Your password should contain at least one special character")
    else:
        print ("Password verified")

Answer 1

您对re.match()的使用有几个方面存在缺陷。相反，我会提出一个不同的策略：

elif set("£$%^&*()").isdisjoint(password):

这会将您的特殊字符串转换为set个字符，然后检查密码中是否 disjoint ...即，如果它不共享任何元素密码。如果这是真的，那么您就知道密码中没有出现任何特殊字符，因此可以继续进行。
