Importing function from another notebook

In this guide, We will walk you through two methods to achieve this: using a package to import directly from a notebook, and saving your functions to a Python file and importing them as a module.

Importing from a Python file

The most straightforward and recommended method is to save your functions in a Python file (.py) and then import them into your notebooks. Here’s how to do it:

another_file.py

def greetFromAnotherFile(name):
    return f"Sup, {name} from another file!"

Notebook 1

import sys
import importlib # !pip install importlib
sys.path.append('.')

import another_file
importlib.reload(another_file)

print(another_file.greetFromAnotherFile(name))

Importing from another notebook

another_notebook

def greetFromAnotherNotebook(name):
    return f"Hello, {name} from another notebook!"

After writing a function or anything else that you would want to use in another notebook you will need to export the Deepnote Notebook into .ipynb file and than drag and drop it into files.

Notebook 1

import ipynb
%run imported_another_notebook.ipynb
print(greetFromAnotherNotebook(name))

Example project structure

├── Notebook 1
├── another_notebook

----------------------------------------------------------------------------------
.
├── work/
		├── requirements.txt
		├── another_file.py
		├── imported_another_notebook.ipynb #after exporting
		└── .deepnote

Examples

For the showcase, I created an example notebook where you can try it yourself and an example app for view.
