Overview of this book

Jupyter Notebook is a web-based environment that enables interactive computing in notebook documents. It allows you to create and share documents that contain live code, equations, visualizations, and explanatory text. The Jupyter Notebook system is extensively used in domains such as data cleaning and transformation, numerical simulation, statistical modeling, machine learning, and much more. This book starts with a detailed overview of the Jupyter Notebook system and its installation in different environments. Next we’ll help you will learn to integrate Jupyter system with different programming languages such as R, Python, JavaScript, and Julia and explore the various versions and packages that are compatible with the Notebook system. Moving ahead, you master interactive widgets, namespaces, and working with Jupyter in a multiuser mode. Towards the end, you will use Jupyter with a big data set and will apply all the functionalities learned throughout the book.

Sample interactive notebook

For this chapter, we will use a simple notebook that asks the user for some information and displays other information.

For example, we could have a script such as this (taken from  Chapter 7 , Sharing and Converting Jupyter Notebooks):

from ipywidgets import interact
def myfunction(x):
    return x
interact(myfunction, x= "Hello World ")

The script presents a textbox to the user with the original value of the box containing the "Hello World" string. As the user interacts with the input field and changes the value, the value of the variable x in the script changes accordingly and is displayed on screen. For example, I have changed the value to the letter A:

We can see the multiuser problem if we just open the same page in another browser window (copy the URL, open a new browser window, paste in the URL, and hit Enter)-we get the exact same display pulling up the last checkpoint. The new window should have started with a new script, just prompting you with the...
