  输入正确的用户名和密码，显示登陆界面，超过三次输入错误则锁定，定义字符串记得加上单引号，数字可以int定义，while循环和if循环语句后加上:，break不加:

print("---------Welcome to Memory Card Hotel!-------")  _username = 'wryyy'  _password = 123  count = 0  while count <3:      username = input("username:")      password = int(input("password:"))      if _username == username and _password == password:          print("Logining now...Welcome {name}!".format(name = _username))          break      else:          print("Invalid username or password.")          count = count +1  else:      print("LOCKED ON,you have tried too many times.")
