博客园开篇,自己开发的双色球小助手
很早就知道“博客园”这个程序员之家,但是一直没有注册,一是因为没有什么好的代码分享的,而是自己虽然系统的学过编程,但是毕业后没有干这行,现在也是自己兴趣爱好,以及工作所需,写写小程序,所以注册个博客,记录一些代码,顺便和大家交流交流!
开篇就分享个自己写的小程序——双手球小助手。这个软件仅仅是自己的练手和杀号辅助工具,没有复杂的算法,因为我还不懂,也不信开奖号码能算出来。
先上图:
这个是直接浏览的网页数据,未做任何处理的。
这个是抓取的网页数据,代码在文章最后。
模拟的双色球选号,素材没找好,颜色偏重。双色的注数的计算代码见文章最后。
这个是定胆杀号,玩双色球的都懂的,能缩小投注范围。
代码:
片段1:
