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.

14.2 Cats and commas

The City of Greater Dandenong in Australia freely provides data about the cats that have been registered with the city as of January 6, 2021. [CAT] Greater Dandenong is in the state of Victoria and is a suburb of Melbourne. [DAN]


The file is in CSV format, which means that commas separate the values on each line. You may think of the commas as separating columns of data. Each row of data contains the information about one cat.

We can peek at the file by opening it in a text editor or using the read function to examine the lines at the beginning of the file. The first line is not data but is a list of the labels or headings for each column.

cats = open("src/examples/registered-cats.csv", "rt")
