1. 生成源码

复制代码 代码如下:

# -*- coding: utf-8 -*-

import random

def generate_verification_code():
    ''' 随机生成6位的验证码 '''
    code_list = []
    for i in range(10): # 0-9数字
        code_list.append(str(i))
    for i in range(65, 91): # A-Z
        code_list.append(chr(i))
    for i in range(97, 123): # a-z
        code_list.append(chr(i))

    myslice = random.sample(code_list, 6)  # 从list中随机获取6个元素,作为一个片断返回
    verification_code = ''.join(myslice) # list to string
    # print code_list
    # print type(myslice)
    return verification_code

def generate_verification_code2():
    ''' 随机生成6位的验证码 '''
    code_list = []
    for i in range(2):
        random_num = random.randint(0, 9) # 随机生成0-9的数字
        # 利用random.randint()函数生成一个随机整数a,使得65         # 对应从“A”到“Z”的ASCII码
        a = random.randint(65, 90)
        b = random.randint(97, 122)
        random_uppercase_letter = chr(a)
        random_lowercase_letter = chr(b)

        code_list.append(str(random_num))
        code_list.append(random_uppercase_letter)
        code_list.append(random_lowercase_letter)
    verification_code = ''.join(code_list)
    return verification_code

if __name__ == '__main__':
    code = generate_verification_code()
    code2 = generate_verification_code2()
    print code
    print code2

其中的一个生成结果如下:
