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.

6.13 Summary

Functions allow you to save sequences of Python expressions and statements and reuse them. You can parameterize a function, which means that its behavior might change based on the arguments you give it.

There is rarely only one way to accomplish a task, and we saw that the choice of algorithm could strongly influence a function’s execution time. Python is well-tuned for iterative operations, and you should use recursion carefully.

All our functions have taken arguments and returned objects that were built into Python by its developers. They have operated on numbers, strings, tuples, lists, sets, and dictionaries. In the next chapter, I introduce classes and the objects we construct with them. A function we define within a class goes by a new name: method.
