基本python密码保险库，回答重复不停止和其他问题

Question

我的评估是构建一个密码保险库，包括基本的python列表，功能while循环等，但在用户实际为其应用程序输入密码的部分遇到问题。第一个问题是，当他们要求查看他们的密码并且没有任何应该说"you have nothing stored"时，它说这个但不要停止重复它，并且还想知道我是否可以得到一些帮助来完成其余部分。这就是我希望这部分代码在使用它时的样子。

按：1）找到您现有的密码2）为您的应用程序保存一个新密码3）查看密码锁的摘要4）成功退出密码锁2

网站名称：Facebook

网站用户名：bob91

网站密码：bob95

你想添加另一个应用程序：是的

网站名称：Instagram

网站用户名：albert91

网站密码：albert95

你想添加另一个应用程序：没有

按：1）找到您现有的密码2）为您的应用程序保存新密码3）查看密码锁的摘要4）成功退出密码锁1您想要访问哪个应用程序密码：Facebook Facebook

用户名：bob91

密码：bob95

locker_menu_func()

Answer 1

我用字典来存储密码。试试这种方式。如果它解决了你的问题，请亲自投票并将其作为答案。

app_passwords = {}

def locker_menu_func():
    print('''You have opened the locker, 
Please select what you would like to do,''')

    while True:
        locker_menu_var = input('''Press: \n1) find your existing passwords \n2) save a new password for your apps
3) see a summary of your password locke \n4) exit password locker successfully''')
        if locker_menu_var == "1":
            while len(app_passwords) < 1: 
                print('''you hve nothing stored''')           
                break
            else:
                for kv in app_passwords.items():
                    a=  kv[0],kv[1]
                    print(str(a).replace("(","").replace(")","").replace("[","").replace("]",""))
                #print (app_passwords)

        elif locker_menu_var == "2":
            web = input("Enter Website")
            username = input("Enter username")
            password = input("Enter password")
            app_passwords[web]=["username:"+username+","+"password:"+password]
        elif locker_menu_var == "3":
            print ("Count of Websites stored",len(app_passwords))
        elif locker_menu_var == "4":
            break
