简单的python登陆接口代码

最近在学习pyhon3.5，写了一段简单的登陆接口代码，勉强比hello world高级一点，用户名密码错误三次就禁止登陆

#/usr/bin/env python
# -*- coding:utf-8 -*-

username = "test"
password = "123456"
count = 0
while count<3:
    name = input("用户名：")
    passwd = input("密码:")
    if username == name and password == passwd:
        print("welcome user {name} login...".format(name=username))
        break
    else:
        print("Invalid username or password!")
    count +=1
    if count == 3:
        print("you are Prohibit landing")
        break
