Dancing with Python

By: Robert S. Sutor

Overview of this book

Dancing with Python helps you learn Python and quantum computing in a practical way. It will help you explore how to work with numbers, strings, collections, iterators, and files. The book goes beyond functions and classes and teaches you to use Python and Qiskit to create gates and circuits for classical and quantum computing. Learn how quantum extends traditional techniques using the Grover Search Algorithm and the code that implements it. Dive into some advanced and widely used applications of Python and revisit strings with more sophisticated tools, such as regular expressions and basic natural language processing (NLP). The final chapters introduce you to data analysis, visualizations, and supervised and unsupervised machine learning. By the end of the book, you will be proficient in programming the latest and most powerful quantum computers, the Pythonic way.

Organizing Objects into Classes

The creative mind plays with the objects it loves.

—Carl Jung, Psychological Types

Although we previously grouped several expressions into collections, such as lists and dictionaries, they don’t have the natural feel or use of built-in types like integers or strings. Are you limited to only those core objects that come with Python? Can you construct new kinds of things complete with operations you can perform on them? Can you hide the data you use and the way you operate on it? If you want to extend an object with additional data or operations, can you do it?

Of course you can, or this chapter would not exist! In what follows, I describe how to create classes and the objects, or instances, that belong to them. A function that operates on class instances gets a new name: method. By careful definition of a class, you can hide its internal information and how you manipulate...
