本文实例讲述了Python编程生成随机用户名及密码的方法。分享给大家供大家参考,具体如下:
方案一:
import random global userName,userPassword #为了便于使用,定义为全局变量 userName = "" userPassword = "" def get_userNameAndPassword(): global userName, userPassword usableName_char = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/" #可作为用户名的字符 usablePassword_char ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890" #可作为密码的字符,根据所需可适当增减 e_userName = [] #定义一个临时List变量,使用list.append添加字符 e_userPassword = [] for i in range(8): e_userName.append(random.choice(usableName_char)) for j in range(6): e_userPassword.append(random.choice(usablePassword_char)) print"e_userName = ", e_userName #输出用户名字符list print"e_userPassword = ", e_userPassword #输出密码字符list userName = "".join(e_userName) userPassword = "".join(e_userPassword) try: get_userNameAndPassword() print "用户名:", userName print "密码:", userPassword except Exception, e: print e.reason
程序输出:
e_userName = ["q", "M", "2", "R", "B", "}", "6", "="] e_userPassword = ["T", "O", "4", "C", "H", "."] 用户名: qM2RB}6= 密码: TO4CH.
方案二(省去中间变量):
#coding=utf-8 import random global userName,userPassword #为了便于后面使用,定义为全局变量 userName = "" userPassword = "" def get_userNameAndPassword(): global userName, userPassword #8位用户名及6位密码 userName = "".join(random.sample("1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/",8)) userPassword = "".join(random.sample("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890",6)) try: get_userNameAndPassword() print "用户名:", userName print "密码:", userPassword except Exception, e: print e.reason
程序输出:
用户名: GweV?2um 密码: fwiOZL
常用第二种方法,直观简便。
