Python实现简单登录验证
本文实例为大家分享了简单的Python登录验证，供大家参考，具体内容如下
编写登录接口
要求：1、输入用户名密码
2、认证成功后显示欢迎信息
3、输错三次后锁定
#coding=utf-8
__author__='wangwc'
importsys,os
count=0
locked=0
mark_user=0
mark_passwd=0
#获取路径
defcur_file_dir():
path=sys.path[0]
ifos.path.isdir(path):
returnpath
elifos.path.isfile(path):
returnos.path.dirname(path)
#print(cur_file_dir())
path=cur_file_dir()
#print(path)
path1=path.replace("\\",'/')+'/'
#print(path1)
#path2=path1+'/'
#循环输入
whilecount<3:
