在Python中链接用户名和密码

Question

我编写了一段练习代码，要求用户从这个模拟数据库中输入用户名和密码。我的问题是如何使任何给定用户的用户名与密码相关联？所以用户“amy”的密码将是“apple”。我是否只需要一个变量设置作为字典，或者类似的东西？

list= ["amy", "chris", "jake"]

password = ["apple", "orange", "date"]

login = ("")

counter = 0

attempts = 5

out_of_attempts = False

while login not in list and not (out_of_attempts):

    if counter < attempts:

        login = input ("enter username: ")

        counter += 1

    else:

        out_of_attempts = True

if out_of_attempts:

        print ("Sorry login limit exceeded please try again later")

else:

        pass

        

while login not in password and not (out_of_attempts):

        if counter < attempts:

            login = input ("now password please: ")

            counter += 1

        else:

            out_of_attempts = True

    

            

if out_of_attempts:

        print ("sorry password limit exceeded, try again later")

else:

    print ("thank you please wait")

Answer 1

是的，字典设置会更好：auth&nbsp;=&nbsp;{'amy':&nbsp;'apple'....等等。代码修改不会那么难。获取用户的密码（也可以使用它来设置）auth[login]

Answer 2

您的用户名/密码的等效“映射”可以如下完成：credentials = {&nbsp; &nbsp; 'amy': 'apple',&nbsp; &nbsp; 'chris': 'orange',&nbsp; &nbsp; 'jake': 'date',}这些允许您快速“检查”，例如：（username in credentials返回True或False）查看用户名是否有密码；credentials[username]使用等获取给定用户名的密码。

Answer 3

简单、稍微安全的方式，让您存储的不仅仅是密码import hashlibdb = {}hash = lambda x: hashlib.md5(x.encode()).hexdigest()def register(user, password, mail):&nbsp; &nbsp; db[user] = {"password": hash(password), "mail": mail}def login(user, password):&nbsp; &nbsp; if db[user]["password"] == hash(password):&nbsp; &nbsp; &nbsp; &nbsp; print("success!")&nbsp; &nbsp; else:&nbsp; &nbsp; &nbsp; &nbsp; print("fail")register("ironkey", "password123", "[e-mail]")login("ironkey", "password")login("ironkey", "password123")# get credentials for the user ironkeyprint(db["ironkey"])failsuccess!{'password': '482c811da5d5b4bc6d497ffa98491e38', 'mail': '[e-mail]'}
