编写登陆接口

代码如下：

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

count = 0

name = "hx"
passwd =   "123"


f = open (‘user_black‘,‘r‘ )
lock_file = f.read()
f.close()

name = input("请输入用户名:")

for i in range(1):
   if lock_file ==  name:
      print ("sorry,锁定了")
      exit()
   else:
      continue

for i in range(3):
   passwd = input("请输入密码:")
   if passwd == "123":
      print ("welcome")
      break
   else:
      print ("登录失败!")
      count += 1
      
if count == 3:                      
   print("用户已锁定")
   f = open (‘user_black‘,‘w‘ )
   f.write(‘%s‘%name)
   f.close()
