本文实例为大家分享了python实现抽奖小程序的具体代码,供大家参考,具体内容如下
设计一个抽奖服务
背景:有x个奖品,要求在y天内发完;每天至少发放z个奖品;每天抽奖人数不定,事先会假设一个范围是m-n
举例:有100个奖品,要求5天内发完,每天至少发15个奖品;每天来抽奖的人估计是 2000-3000 人,希望奖品能够比较均匀,但随机的抽取出来。
接口要求:服务监听一个端口,测试程序不断连接,发送一个数字代表是第几天,比如第1-2000个请求发送1(模拟第一天来了2000人),第2001到5000请求发送2(模拟第二天来了3000人)... 服务返回 0 or 1 表示是否抽到奖品
client.py:设置初始化参数,模拟用户向server端发送数据
