如何编写一个知道细胞输入编号的细胞魔术? [英] How to write a cell magic that knows the input number of the cell?

问题描述

有没有一种方法可以知道单元格的输入编号，从而编写出一个单元魔术? 输入数字"是指单元格In[?]前缀中的?.乍一看，IPython.core.magic.cell_magic似乎只知道单元格的内容-除此之外还有什么办法吗?

Is there a way to write a cell magic that knows the input number of the cell? By "input number" I mean the ? in the cell's In[?] prefix. At first glance, it seems that IPython.core.magic.cell_magic only knows about the cell content -- it there any way to go beyond that?

推荐答案

此信息由IPython shell的当前实例的execution_count提供，可以通过get_ipython获得:

This information is provided by the execution_count of the current instance of the IPython shell, that can be obtained with get_ipython:

print(get_ipython().execution_count)
