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.

2.4 Variables and assignment

If we wanted to assign a reusable name to the list of ages, what might be suitable? Well, “ages” starts with “a”, so we could use “a”. However, that’s not very descriptive. What if we also had a list of kinds of apples? Or the names of your aunts? A good and descriptive name is ages itself. We make the association between the name and the data using an equal sign “=”.

ages = [12, 16, 19]

This is an assignment, and ages is a variable. The name of the variable is an example of an identifier. We assign the value [12, 16, 19] to the variable ages. Python produces no output from an assignment.

If we type the variable name into the Python interpreter, we get the list we assigned to it.

ages
[12, 16, 19]

We compute the number of elements in the list using the Python built-in len function. [PYB...
