jupyter笔记本可以找到自己的文件名吗? [英] Can a jupyter notebook find its own filename?

问题描述

jupyter笔记本是否有可能获得自己的文件名，这与我们从python脚本执行的操作类似?

Is it possible for a jupyter notebook to get the name of its own file, similarly to what we would do from a python script?

os.path.basename(__file__)似乎不起作用，至少对于jupyterlab上的我而言

os.path.basename(__file__) doesn't seem to work, at least for me on jupyterlab

sys.argv[0]返回my_home/anaconda3/lib/python3.6/site-packages/ipykernel_launcher.py

推荐答案

我发现的唯一方法是通过JavaScritp，如下所示 此答案.

The only way I've found is through JavaScritp as in this answer.

紧凑形式是一个像这样的单元格:

The compact form is a cell like this:

%%javascript
IPython.notebook.kernel.execute(`notebookName = '${window.document.getElementById("notebook_name").innerHTML}'`);

之后，您将获得变量notebookName，其名称显示在 页面顶部.

after that you'll have the variable notebookName with the name that appears at the top of the page.

更好的解决方案可能是使用IPython.notebook.notebook_name:

A better solution may be using IPython.notebook.notebook_name:

%%javascript
IPython.notebook.kernel.execute(`notebookName = '${IPython.notebook.notebook_name}'`);

它为您提供扩展名.ipynb
