In Kaggle, where can I store common code to be imported into multiple Notebooks?

Question

I am working on the Kaggle HuBMAP competition. My application consists of several components -- Preprocessing, Training, Prediction and Scoring -- and there is common code that is used by more than one component. Currently, I put multiple copies of the common code in the Notebooks for each of the components, but I'd like to maintain one copy of the common code that I can import into my application components.

My question is: Where do I store that common code so that it can be imported? Does it go in a separate DataSet? Or a separate Notebook? How do I store it? How do I import it?

Figured out how to do it:

Create a file like common_code.py to hold the code you want to import in Kaggle
Create a Kaggle DataSet like CommonCode and upload common_code.py to it
In the Notebook where you want to import the common code add the DataSet CommonCode
At the top of your Notebook, add the following code:

import sys sys.path.append( "/kaggle/input/CommonCode" )

Then, at any subsequent point in the Notebook you can say

from common_code import *

While this shows an example of a single import-able file, you can use it for any number of files, and you can update the DataSet for additions or revisions.
