如何检查代码是否在 IPython notebook 中执行? [英] How can I check if code is executed in the IPython notebook?

问题描述

我想分享一些 Python 代码示例，如果在终端 Python/IPython 或 IPython 笔记本中执行，它们应该会做一些不同的事情.

I have some Python code example I'd like to share that should do something different if executed in the terminal Python / IPython or in the IPython notebook.

如何检查我的 Python 代码是否在 IPython notebook 中运行?

推荐答案

问题是您希望以不同的方式执行什么.

The question is what do you want execute differently.

我们在 IPython 中尽最大努力防止内核知道连接到哪种前端，实际上您甚至可以让内核同时连接到许多不同的前端.即使您可以通过查看 stderr/out 的类型来了解您是否在 ZMQ 内核中，它也不能保证您在另一端拥有什么.你甚至可以根本没有前端.

We do our best in IPython prevent the kernel from knowing to which kind of frontend is connected, and actually you can even have a kernel connected to many differents frontends at the same time. Even if you can take a peek at the type of stderr/out to know wether you are in a ZMQ kernel or not, it does not guaranties you of what you have on the other side. You could even have no frontends at all.

您可能应该以独立于前端的方式编写代码，但是如果您想显示不同的内容，可以使用 丰富的显示系统(链接固定到 IPython 4.x 版) 根据前端显示不同的东西，但前端会选择，而不是库.

You should probably write your code in a frontend independent manner, but if you want to display different things, you can use the rich display system (link pinned to version 4.x of IPython) to display different things depending on the frontend, but the frontend will choose, not the library.
