Overview of this book

Jupyter has garnered a strong interest in the data science community of late, as it makes common data processing and analysis tasks much simpler. This book is for data science professionals who want to master various tasks related to Jupyter to create efficient, easy-to-share, scientific applications. The book starts with recipes on installing and running the Jupyter Notebook system on various platforms and configuring the various packages that can be used with it. You will then see how you can implement different programming languages and frameworks, such as Python, R, Julia, JavaScript, Scala, and Spark on your Jupyter Notebook. This book contains intuitive recipes on building interactive widgets to manipulate and visualize data in real time, sharing your code, creating a multi-user environment, and organizing your notebook. You will then get hands-on experience with Jupyter Labs, microservices, and deploying them on the web. By the end of this book, you will have taken your knowledge of Jupyter to the next level to perform all key tasks associated with it.

Using ipywidgets

ipywidgets is a set of widgets produced as part of the Jupyter project. As such, I would expect their use and number to increase with the project's popularity.

Getting ready

ipywidgets can also be installed with conda using:

conda install -c conda-forge ipywidgets

There are pip install commands available as well.

Using an ipywidget

I picked the radio button widget as an example.

How to do it...

We can use this code:

import ipywidgets as widgets

widgets.RadioButtons(
 options=['red', 'green', 'blue'],
 description='Balloon color:',
 disabled=False
)

This displays as:

How it works...

All of the individual widgets work the same:

Import the reference of the widget type you want to use
Instantiate the widget using its parameters
Optionally add handling to take a new value from the widget

In this example, we are using the Python convention of importing the entire library and calling it widgets. Then we use a specific widget type by referencing it via the dot notation. Each of the widget types...
