My app Qubiter has a folder full of Jupyter notebooks (27 of them, in fact). Opening a notebook takes a short while, which is slightly annoying. I wanted to give Qubiter users the ability to peek inside all the notebooks at once, without having to open all of them. Qubiter’s new SUMMARY.ipynb notebook allows the user to do just that.
SUMMARY.ipynb scans the directory in which it lives to find all Jupyter notebooks (other than itself) in that directory. It then prints for every notebook it finds (1) a hyperlink to the notebook, and (2) the first cell (which is always markdown) of the notebook. This way you can read a nice, automatically generated summary of all the notebooks without having to open all of them. If you find a notebook that you want to explore further, you can simply click on its link to open it.
Here is the code that I use. I posted it on StackOveflow
And here is Qubiter's notebook using the code:
