continue语句、while循环

_username = "gsk"
_password = "123a"
num = 0
while num < 3:
    username = input("请输入用户名：")
    password = input("请输入密码")
    if username == _username and password == _password:
        print("爱你 %s login..." %_username)
        break
    else:
        print("用户名或密码输入错误")
    num += 1
else:
    print("输入次数超过三次")

 

 

 

 

添加判断，选择是否继续玩

_username = "gsk"
_password = "123a"
num = 0
while num < 3:
    username = input("请输入用户名：")
    password = input("请输入密码")
    if username == _username and password == _password:
        print("爱你 %s login..." %_username)
        break
    else:
        print("用户名或密码输入错误")
    num += 1
    if num == 3:
        sum = input("还想继续玩吗[y/n]")
        if sum == "y":
            num =0
else:
    print("输入次数超过三次")
