输入用户名和密码，并进行判断：若是输入正确，提示成功登陆；若是不正确，提示错误用户名和密码。

coding:

import getpass

_username = 'john'
_passwd = '123'
user = input("please enter your name:")
passwd = input("please enter your password:")
if user == _username and passwd == _passwd:
    print("welcome user %s login!"% user)
else:
    print("you entered wrong username or password!")


超过3次，提示锁定用户

coding:

import getpass 

count = 0_username = 'john'_passwd = '123'while count <3:    user = input("please enter your name:")    passwd = input("please enter your password:")    if user == _username and passwd == _passwd:        print("welcome user %s login!"% user)    else:        print("you entered wrong username or password!")    count +=1print("your username now locked!")
