python唯一用户名和密码

我想把这个代码变成一个代码，可以存储用户的用户名和密码以及每个用户的详细信息

name = (input('what is your name '))
age = (input('what is your age '))
(print('please wait your username is processing...'))
import time
time.sleep(5)
(print(name[:3]+age))
password1 = (input('what is your password '))
(print('your details are saved. You can now log in'))
import time
time.sleep(3)
(input('What is your username')
username == name
(input('what is your password')
password = password1
 (print('you are now logged in')

用最简单的术语，您可以将输入存储在Python字典中，将用户名作为密钥，密码作为值，例如：

user = dict()
user.update({name:password1})

通过将其存储在字典中，可以确保用户名始终是唯一的。当您想要匹配用户名输入时，您可以执行以下操作：

if username in user:
  //do some processing
