利用python实现简单随机验证码

1 #！/usr/bin/env python
2 # -*- coding:utf-8 -*-
3 import random
4 temp =''
5 for i in range(6):
6     num = random.randrange(0,4)
7     if num ==3 or num == 1:
8         rad2 = random.randrange(0,10)
9         temp = temp + str(rad2)
10     else:
11         rad1 = random.randrange(65,91)
12         c1 = chr(rad1)
13         temp = temp + c1
14
15 print(temp)
