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.

7.17 Creating modules

We have seen many expressions, variable assignments, and function and class definitions. When you put those together in a file, you get a Python module. For example, in Appendix D, I group the class definitions that we developed for guitars in section 7.13 on inheritance.

The name of your module file should be a valid Python name followed by “.py”. My module with Guitar and other classes is guitar. In particular, do not use hyphens in your module name because Python will think you are subtracting.

The “top level” of a module is code that exists outside any function or class definition. It starts in column 1. Everything we have seen about constants, global variables, and name mangling applies to top-level code.

Bring the top-level contents of your module into other modules or your interactive environment by using import and from, as we discussed...
