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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17

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:
1
2
3
4
|
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):
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

#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:
1
2

用户名: GweV? 2um 密码: fwiOZL |
常用第二种方法,直观简便。
注:(本例在python2.7下测试正常运行。)
希望本文所述对大家Python程序设计有所帮助。
