How to run Python code before every jupyter notebook kernel

Question

Suppose I have a code snippet that I\'d like to run every time I open a jupyter notebook (in my case it\'s opening up a Spark connection). Let\'s say I save that code in a .

Answer 1

I'd recommend to create a startup file as you suggested, and include it via

%load ~/.jupyter/startup.py

This will paste the content of the file into the cell, which you can then execute.

Alternatively, you can write a minimal, installable package that contains all your startup code.

Pro: Doesn't clutter your notebook

Con: More difficult to make small changes.
