python学习——生成cdkey小程序

本小程序用来生成形如acf3-ssh3-22sh-jjis-hsha-yysh的cdkey

#!/usr/bin/env python
# coding=utf-8
import string
import random

#源字符串
data = string.letters + string.digits

#获取子串形如axf6
def get_sub_key(num):
    mystr = random.sample(data, num) #--->['a', 'x', 'f', '6']
    ret_str = "".join(mystr) #--->axf6
    return ret_str

#acf3-ssh3-22sh-jjis-hsha-yysh
def get_key(count, num):
    cd_key = [] #定义一个链表，存放子字符串

    for sub_key in range(count):
        cd_key.append(get_sub_key(num)) #往链表里面增加字符串
        
	#cd_key = ['axF8', 'assd', '1223' ...]

    ret_key = "-".join(cd_key) #用 - 来拼接字符串成acf3-ssh3-22sh-jjis-hsha-yysh
    return ret_key

if __name__ == "__main__":
    print get_key(6, 4)

简化写法

#!/usr/bin/env python
# coding=utf-8
import string
import random

def get_sub_key(num):
    return "".join(random.sample(data,num))

def get_key(count, num):
    return "-".join([get_sub_key(num) for _ in range(count)])

if __name__ == "__main__":
    print get_key(6, 4)
