Jupyter notebook is by far my all time favorite tool. It is the go-to tool for data exploration for any data scientist or data analyst out there. If you are new to the data space and don’t yet know what I am talking about, check out this YouTube video by codebasics.

Jupyter lets us employ extensions to make the environment more suitable for any personality out there. In this post, I am sharing with you my personal Jupyter personalization tips and tricks.

Example of what my Jupyter Notebook environment looks like.

Shell Commands

Shell is a way to interact with the computer through text commands. Of all the shell variants, bash (Born Again Shell) is the most popular and is the default shell for modern implementations of Unix.

When you are working in Jupiter, or any of your other favorite Python IDE, you might find yourself jumping back and forth between your terminal and jupyter window. However, what most people don’t realize is that you can actually run shell commands directly in your Notebook. All you have to do is prefix your shell command with an exclamation mark; “!”.

Example of what the shell commands look like in my Jupiter Notebook.

In addition to simply running shell commands, we can pass values between python and shell like this:

curr_directory = !pwd

files_in_dir = !ls

Jupyter Themes

I am a big fan of a dark theme in my IDE or notebook editors. I was therefore ecstatic when I found out that you could change the look of Jupyter.

Installation

pip install jupyterthemes

List and Chose a Theme

When you have successfully installed jupyterthemes from pip, we want to list the available themes, then select the theme we like the best. In my case, after trying all of them, I chose to go with chesterish. I love the dark background with the blue highlights.

Extensions

Jupiter has a decent size list of extensions that will help make you Jupiter-life simpler.

List of all extensions for Jupyter.

In order to use these extensions, we will need to install them using the following pip and jupyter commands:

pip install jupyter_contrib_nbextensions && jupyter contrib nbextension install

As you can see from the screenshot above, my favorite extensions are as follows:

Collapsible Headings

When you are using markdown headings in your notebook, this extension lets you collapse the section underneath a given header. One of the most valuable extensions I use as it makes the coding environment cleaner.

Hinterland

Hinterland enables code autocompletion as you type in your notebook, as opposed to enabling it with the tab key which Jupyter defaults to. I have found that it was quite annoying in the beginning and that I had to play around with some of the settings.

Snippets

Do you find yourself typing in the same import statements for every notebook? Import Numpy, pandas, seaborn, matplotlib, and so on… This extension lets you input predefined snippets of code into your notebook with only a couple of mouse clicks.

Split Cells Notebook

Split cells notebook allows you to split a cell into multiple columns. There are times when I’ve wanted to have two cells next to each other horizontally, and this allows you to do exactly that.

Table of Contents

This extension adds a section to the left of your notebook which keeps track of all your markdown headings and lets you jump back and forth between them. It also highlights the section that currently has running cells. This is one of the most useful extensions I’ve found. By far my favorite.

Variable Inspector

How many times have you written print(variable) simply because you wanted to double check the value of a variable? The variable inspector collects all your defined variables and displays them in a neat little floating window. The window is draggable, resizable, and collapsible.

Summary

That concludes this blog post on how I have my Jupyter environment set up. I hope you found it helpful and that this will make your life a little bit easier the next time you dive into a notebook.

Let me know if you have any preferences that might be different from mine. Who knows, maybe I will find them useful as well.

I have half a decade of experience working with data science and data engineering in a variety of fields both professionally and in academia. I ahve demonstrated advanced skills in developing machine learning algorithms, econometric models, intuitive visualizations and reporting dashboards in order to communicate data and technical terminology in an easy to understand manner for clients of varying backgrounds.
