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 randomglobal 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:", userPasswordexcept 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-8import randomglobal 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:", userPasswordexcept Exception, e:  print e.reason

程序输出：
