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。
