这篇文章主要介绍了Python如何实现浪漫烟花效果，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

马上虎年了，也是我的生肖年，很激动!（不小心暴露了年龄，哈哈哈......),这里先给大家拜年啦，祝大家虎年快乐，虎年爆富！

首先一首原创诗分享给大家，然后欣赏一下烟花代码，用Python实现的。

魏巍中华龙在飞,能驭其者方可主沉浮,今夕新年，晚风过威奢, 请卿听我歌:

新年傲啸

烟花冲破九霄,

正如神雕在傲啸;

黑夜捅了它一刀;

五彩的血溅在黑夜外套;

于是傲啸浸透夜的衣角;

只愿与卿震响九霄!

龙吟虎啸!
