Python实现账号密码输错三次即锁定功能简单示例
本文实例讲述了Python实现账号密码输错三次即锁定功能。分享给大家供大家参考,具体如下:
初学Python—1
#实现账号输错三次即锁定 user="hubery" passwd="123" confirm=0 lock=0 fileOpen=open("username.txt","a+") fileOpen.seek(0) foriinrange(3): username=input("username:") passsword=input("password:") forlineinfileOpen.readlines(): ifusername==line.strip(): print("账户已经锁定!") lock=1 break else: continue fileOpen.seek(0) ifuser==usernameandlock==0: ifpasswd==passsword: print("欢迎,欢迎!") confirm=1 break else: print("账号户或者密码错误!") continue eliflock==1: continue else: print("1账号或者密码错误!") continue fileOpen.close() ifconfirm==0andlock==0: fileWrite=open("username.txt","a") fileWrite.write(username+"\n") fileWrite.close()
基本功能可以实现;
锁定的账号为第三次输错的用户名(待完善)
以下为完善版本,如有错误,请告知
importos user="hubery" passwd="123" count=0 lock=0 fileOpen=open("username.txt","a+") fileOpen.seek(0) while1: foriinrange(5): username=input("username:") passsword=input("password:") forlineinfileOpen.readlines(): ifusername==line.strip(): print("账户已经锁定!") lock=1 break else: continue fileOpen.seek(0) ifuser==username: iflock==1: continue elifpasssword==passwd: print("欢迎,欢迎!") os._exit(0) elifcount<2: print("账号或者密码错误!") count+=1 continue else: fileOpen.write(username+"\n") fileOpen.flush() print("密码输入错误超过三次,账户已经锁定!") fileOpen.seek(0) continue else: print("账号密码错误!") continue check=input("还想验证其他账户?(yes-继续,no-退出)") if"no"==check.lower(): os._exit(0) else: continue fileOpen.close()
