想到一块儿去了，只不过我打印的是"Life is short"
前几天有了类似想法，这几天用了七八个小时已经写了一大堆了,用了各种各样的高级特性来实现(猴子补丁/装饰器/协程/生成器/...)Life-is-Shortgithub.com
这样写表面看起来是违反Python哲学的，但也可以理解为写Python高级特性的demo顺带print-debug输出点东西，就比较好玩了
要说最长的,这个项目的集成测试就可以理解为“最长的”,因为它是套娃输出.
它用猴子补丁来捕获输出流,以测试其他实现是否正确输出,如果全部通过,就truncate然后释放输出流,最后自己输出"Life is short"，所以无论你有多长的代码，都能塞进这个项目里，变成下面这个集成测试的依赖项。
