Python基本循环实例Day 1

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.")
