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.

Interact widget

Interact is the basic widget that is often used to derive all other widgets. It has variable arguments, and, depending on these arguments, can affect many different variations of user input control.

Interact widget slider

We can use interact to produce a slider by passing in an extent. Take the following script:

from ipywidgets import interact
# define a function to work with (cubes the number)
def myfunction(arg):
    return arg+1
interact(myfunction, arg=9);

Here, we have a script that does the following:

  • References the package we want to use

  • Defines a function (which is called for every user input of a value)

  • Calls out to interact, passing our handler and a range of values

When we run this script, we get a scrollbar that is modifiable by the user:

The user is able to slide the vertical bar over the range of values. The upper end is 27 and the lower end is -9 (assume we could pass additional arguments to interact to set the range of values that are selectable). myfunction is...
