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：
