以编程方式获取当前的Ipython笔记本电脑输出？ [英] Programmatically get current Ipython notebook cell output?

问题描述

我有一个在IPython笔记本（输入单元格X）中运行的导入函数，它生成一个输出（在输出单元格X中）。函数运行后，我有更多的代码（也在输入单元格X中）;有没有办法让代码检索当前输出（在输出单元格X中）？

I have an imported function that runs in an IPython notebook (input cell X) which produces an output (in output cell X). After the function runs, I have some more code (also in input cell X); is there any way for that code to retrieve the current output (in output cell X)?

可能还有其他方法可以实现我想要实现的目标;但如果上述情况可能，我很好奇。

There may be other ways to do what I am trying to achieve; but I am curious if the above is possible.

谢谢！

推荐答案

< IP> IPython的输出缓存系统定义了几个全局变量：

IPython's output caching system defines several global variables:

• [ _ ]（单个下划线）：存储以前的输出，如Python的默认解释器。


• [ __ ]（两个下划线）：下一个上一个。


• [ ___ ]（三个下划线）：next-next previous。

• [_] (a single underscore): stores previous output, like Python’s default interpreter.
• [__] (two underscores): next previous.
• [___] (three underscores): next-next previous.

此外，每次输出后创建 x ，创建一个变量 _< x> ，并将输出作为其值。例如：

Additionally, after each output x is created, there is a variable _<x> created with the output as its value. For example:

In [12]: lst = [i for i in range(11)]

In [13]: lst
Out[13]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

In [14]: _13
Out[14]: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

此外，如果您有兴趣， _i< x> 包含输入单元格的内容 x ：

Also, if you're interested, _i<x> contains the contents of the input cell x:

In [15]: _i12
Out[15]: 'lst = [i for i in range(11)]'
