做为 Apple Store App 独立开发者，你要搞限时促销，为你的应用生成激活码（或者优惠券），使用 Python 如何生成 200 个激活码（或者优惠券）？

在此生成由数字，字母组成的20位字符串

uuid模块

import uuid

def get_id():

    file_object = open('uudi.txt','w+')

    for i in range(200):

        ID = str(uuid.uuid1()) + '\n'

        file_object.write("ID"+str(i+1)+"："+ID)

    file_object.close()

if __name__ == '__main__':

    get_id()

random模块

# coding:utf-8

# python3环境

# 通过多线程来生成200个激活码

import random

import string

import threading

def get_str():

    ran_str = ''.join(random.sample(string.ascii_letters + string.digits, 20))

    return ran_str

class myThread (threading.Thread):

    def __init__(self, threadID, name, counter):

        threading.Thread.__init__(self)

        self.threadID = threadID

        self.name = name

        self.counter = counter

    def run(self):

        print ("开始线程：" + self.name)

        write_id(self.name, 40)

        print ("退出线程：" + self.name)

def write_id(threadName, counter):

    file_object=open('id.txt','a+')

    while counter:

        file_object.write("%s: %s\n" % (threadName+str(counter), get_str()))

        counter -= 1

    file_object.close()

# 创建新线程

thread1 = myThread(1, "Group1-", 1 )

thread2 = myThread(2, "Group2-", 2)

thread3 = myThread(3, "Group3-", 3)

thread4 = myThread(4, "Group4-", 4)

thread5 = myThread(5, "Group5-", 5)

# 开启新线程

thread1.start()

thread2.start()

thread3.start()

thread4.start()

thread5.start()

thread1.join()

thread2.join()

thread3.join()

thread4.join()

thread5.join()

print ("退出主线程")
