What are Jupyter Notebook Extensions?

Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and narrative text. If you're a data scientist or analyst, then you've probably used Jupyter Notebook for a while. While Jupyter Notebook comes with a lot of features and functionality out-of-the-box, there are still times when you need additional functionality that isn't built-in. That's where Jupyter Notebook Extensions come in.

Jupyter Notebook Extensions are Python packages that provide additional functionality to Jupyter Notebook. They can add new menus, toolbars, keyboard shortcuts, and even new cells to your Notebook. They're easy to install and use, and you can choose from hundreds of extensions that are designed to make your life easier.

Installing Jupyter Notebook Extensions

Before we dive into some of the best Jupyter Notebook Extensions for data science, let's quickly cover how to install Jupyter Notebook Extensions. Here are the steps:

  1. Open Terminal or Command Prompt (depending on your OS)
  2. Type in pip install jupyter_contrib_nbextensions && jupyter contrib nbextension install
  3. That’s it! Restart your Jupyter Notebook and you should see the new options in your toolbar.

Now that you know how to install Jupyter Notebook Extensions, let's take a look at some of the best Jupyter Notebook Extensions for data science.

Essential Jupyter Notebook Extensions for Data Science

Table of Contents

As notebooks grow in size, it becomes more difficult to navigate them. This is where the Table of Contents extension comes in. With this extension, you can easily navigate through and find the different sections of your notebook. You can add entries to the Table of Contents either manually or automatically, and you can even add a sub-section to your notebook by using the '##' or '###' markdown syntax.

Collapsible Headings

Another great extension for navigating large notebooks is the Collapsible Headings extension. It allows you to collapse or expand all of the headings at once, making it much easier to find the section you're looking for. The extension also remembers which sections you've collapsed or expanded, even if you close or reopen the notebook.


The Hinterland extension provides code autocompletion suggestions as you type. It uses information from Jupyter's kernel to provide suggestions based on the context of your code. This extension can save you a lot of time by reducing the need to type out long lines of code.

Variable Inspector

The Variable Inspector extension displays all of the Python variables in your notebook, along with their values and data types. It's a great tool for keeping track of your variables and making sure they're being assigned the correct values.

Execute Time

The Execute Time extension displays the execution time for each cell in your notebook. This can be useful for identifying which cells are taking the longest to execute and optimizing your code for speed.

Popular Jupyter Notebook Extensions for Data Science

While the extensions we just covered are essential for any data scientist or analyst using Jupyter Notebook, there are many other extensions that can make your life easier. Here are some popular extensions for data science.

jupyterlab-git Extension

This extension provides Git integration for JupyterLab, allowing you to track changes to your notebooks and collaborate with other users. With this extension, you can easily commit changes, push and pull from remote repositories, and resolve conflicts.

Nbextensions Configuration Editor

This extension provides a graphical user interface for managing your Notebook's extensions. You can enable or disable extensions, configure their settings, and even create your own custom extensions.

Jupyter Notebook Widgets

This extension allows you to create interactive widgets in your notebook. Widgets are graphical user interface (GUI) elements that allow users to interact with data in real-time. With Jupyter Notebook Widgets, you can create sliders, dropdown menus, checkboxes, and more.

TortoiseHg Extension

If you use Mercurial for version control instead of Git, then the TortoiseHg extension is for you. It provides Mercurial integration for Jupyter Notebook, allowing you to track changes to your notebooks and collaborate with other users.


Jupyter Notebook Extensions are a powerful tool for data scientists and analysts. They can save you time and improve your productivity by adding new functionality to your Notebook. In this article, we covered some of the essential and popular Jupyter Notebook Extensions for data science, including Table of Contents, Collapsible Headings, Hinterland, Variable Inspector, Execute Time, jupyterlab-git Extension, Nbextensions Configuration Editor, Jupyter Notebook Widgets, and TortoiseHg Extension.

There are hundreds of other extensions available, and we encourage you to explore them and find the ones that best suit your needs. With the right extensions installed, you can take your data science workflow to the next level!
