Python实现账号密码输错三次即锁定功能简单示例

#实现账号输错三次即锁定user = "hubery"passwd = "123"confirm = 0lock=0fileOpen = open("username.txt","a+")fileOpen.seek(0)for i in range(3): username = input("username:") passsword = input("password:") for line in fileOpen.readlines():  if username == line.strip():   print("账户已经锁定！")   lock=1   break  else:   continue fileOpen.seek(0) if user == username and lock ==0:  if passwd == passsword:   print("欢迎，欢迎！")   confirm = 1   break  else:   print("账号户或者密码错误！")   continue elif lock==1:  continue else:  print("1账号或者密码错误！")  continuefileOpen.close()if confirm == 0 and lock==0: fileWrite=open("username.txt","a") fileWrite.write(username+"/n") fileWrite.close()
