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.

A.3 Installing Python modules and packages

PyPI is the “Python Package Index” and contains over 300,000 modules and packages that you can download and import. You can browse and search this catalog at

The pip application downloads and manages PyPI packages on your system. Use either pip or pip3 from the command line to start the application. I refer to pip in what follows to demonstrate several of its capabilities. When you run these commands, your output will likely be different from what I show here because I have other packages installed. If you are curious, I list the Python packages on my machine in Appendix F, Production Notes.
