我正在尝试编写根据用户要求生成密码的密码生成器。如果用户输入超过两次 yes 并不总是有效。并非所有要求都包含在函数创建的密码中。我很想知道如何解决这个问题并得到解释。

from random import randint
from secrets import choice
    def PasswordGenerator():
        print("Welcome to Password Generator\nYou can create a password with capital letters, lowercase letters, numbers, and special characters.\nDuring the password creation process, we will ask you which password you want.\n")
        while True:
            try:
                length = int(input("Please enter the length of the password you want to create:\nNote: The minimum length is 8 characters And enter Only integers\n"))
                while length < 8:
                    print("The minimum password length is 8 characters, please enter a valid integer number ")
                    length = int(input("Enter the length of the password you want to create:\n"))
                password_uppercase = input("Answer only with yes or no.\nDo you want upper case? \n")
                while password_uppercase != "yes" and password_uppercase != "YES" and password_uppercase != "no" and password_uppercase != "NO":
                    password_uppercase = input("Answer only with yes or no.\nDo you want upper case? \n")
                password_lowercase = input("Answer only with yes or no.\nDo you want lower case?\n")
                while password_lowercase != "yes" and password_lowercase != "YES" and password_lowercase != "no" and password_lowercase != "NO":
                    password_lowercase = input("Answer only with yes or no.\nDo you want lower case?\n")
                password_numbers = input("Answer only with yes or no.\nDo you want numbers?\n")
                while password_numbers != "yes" and password_numbers != "YES" and password_numbers != "no" and password_numbers != "NO":

                    password_special = input("Answer only with yes or no.\nDo you want Special symbols?\n")
            except ValueError:
                print("Enter Only integers")
            except:
                print("Oops you got an error! Please enter a VALID value")
            else:
                alphabet = ''
                if password_numbers == "yes":
                    alphabet += "0123456789"
                elif password_numbers == "YES":
                    alphabet += "0123456789"
                if password_uppercase == "yes":
                    alphabet += "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

                password = "".join(choice(alphabet) for x in range(randint(length, length)))
                return password
                break

由于您正在创建一个完整的字母表并从中随机选择字符，因此不能保证从每个组（数字、大写字母等）中至少选择一个。

您可以通过在字母表中将组分开来修复它。然后从每个中选择至少一个。最后，您应该将字符洗牌一次，以确保字母表中的顺序在生成的密码中丢失。

import random

    print("Welcome to Password Generator\nYou can create a password with capital letters, lowercase letters, numbers, and special characters.\nDuring the password creation process, we will ask you which password you want.\n")
    try:
        length = int(input("Please enter the length of the password you want to create:\nNote: The minimum length is 8 characters And enter Only integers\n"))
        while length < 8:
            print("The minimum password length is 8 characters, please enter a valid integer number ")
            length = int(input("Enter the length of the password you want to create:\n"))
        password_uppercase = input("Answer only with yes or no.\nDo you want upper case? \n")
        while password_uppercase != "yes" and password_uppercase != "YES" and password_uppercase != "no" and password_uppercase != "NO":

        random.shuffle(password_chars) # shuffle to lose the order of groups from the generated list
        return "".join(password_chars)

print(PasswordGenerator())

输出：
