Who loves debugging things that only fail occasionally? Just me? Maybe you need to check out Andy Jones’ extract() function that “magically” extracts a caller’s environment into an IPython interpreter session. Mix in a little post-mortem debugging with Jupyter’s %debug magic command, and you’ll be painlessly debugging finicky code in no time.
(
是也乎:神奇的事后验尸,extract()能将调用者环境装配人 Jupyter 进行细致的检验. )

是也乎:一个系列, 刚刚发布第一篇, 1: 数据科学的笔记本 /2: 2020我的笔记本 /3: 笔记本的未来.. 是的, 笔记本从实体的, 到电脑形态, 现在又是一种可计算文档的指代了… 其实, 对 Jupyter 的发展是看好的, 但是, 对其最终产品形态不明朗, 因为 notebook 形式非常创意的将 开发/调试/笔记/发行 很好的揉合在一起; 唯独没对运行时有考虑…这就比较尴尬了…
