import random global userName,userPassword #為了便于使用，定義為全局變量 userName = '' userPassword = '' def get_userNameAndPassword(): global userName, userPassword usableName_char = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/" #可作為用戶名的字符 usablePassword_char ="abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890" #可作為密碼的字符，根據所需可適當增減 e_userName = [] #定義一個臨時List變量,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 #輸出用戶名字符list print"e_userPassword = ", e_userPassword #輸出密碼字符list userName = ''.join(e_userName) userPassword = ''.join(e_userPassword) try: get_userNameAndPassword() print "用戶名:", userName print "密碼:", userPassword except Exception, e: print e.reason

程序輸出：

e_userName = ['q', 'M', '2', 'R', 'B', '}', '6', '='] e_userPassword = ['T', 'O', '4', 'C', 'H', '.'] 用戶名: qM2RB}6= 密碼: TO4CH.

方案二（省去中間變量）：

#coding=utf-8 import random global userName,userPassword #為了便于后面使用，定義為全局變量 userName = '' userPassword = '' def get_userNameAndPassword(): global userName, userPassword #8位用戶名及6位密碼 userName = ''.join(random.sample("1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()_+=-><:}{?/",8)) userPassword = ''.join(random.sample("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_.1234567890",6)) try: get_userNameAndPassword() print "用戶名:", userName print "密碼:", userPassword except Exception, e: print e.reason

程序輸出：

用戶名: GweV?2um 密碼: fwiOZL

常用第二種方法，直觀簡便。
