python-day1

设计一个登陆接口，连续三次输入不正确，强制退出，不让继续尝试，并记录下用户名，下次禁止登陆。

 

 

_username = "test"
_password = "test"

count = 1

while count <= 3:
    username = input("input your username: ")
    password = input("input your password: ")
    f1 = open('D:\py\day1\denglu.txt', 'r')
    if username in f1:
        print("you hava try more than three times")
        break
    else:
        if username == _username and password == _password:
            print("you login sucessful")
            break
        else:
            print("please input the right username ")
            count +=1
else:
    f = open('D:\py\day1\denglu.txt', 'w+')
    f.write(username)
    f.close()
