Overview of this book

Python is among the most popular programming languages in the world. It’s ideal for beginners because it’s easy to read and write, and for developers, because it’s widely available with a strong support community, extensive documentation, and phenomenal libraries – both built-in and user-contributed. This project-based course has been designed by a team of expert authors to get you up and running with Python. You’ll work though engaging projects that’ll enable you to leverage your newfound Python skills efficiently in technical jobs, personal projects, and job interviews. The book will help you gain an edge in data science, web development, and software development, preparing you to tackle real-world challenges in Python and pursue advanced topics on your own. Throughout the chapters, each component has been explicitly designed to engage and stimulate different parts of the brain so that you can retain and apply what you learn in the practical context with maximum impact. By completing the course from start to finish, you’ll walk away feeling capable of tackling any real-world Python development problem.

Python 3.8

Python 3.8 was released in October 2019, received bug fixes until May 2021, and will receive security patches until October 2024.

Assignment expression

One of the most known additions to Python 3.8 is the assignment expression, also known as the walrus operator. It was quite a controversial addition to Python, which many people attribute to the stepping down of Guido van Rossum from the Python’s final decision-making role in the CPython evolution.

This new syntax allows developers to write an assignment in the place of an expression. This allows for shorter code by combining what otherwise needs to be multiple lines of code. This is quite useful in control flow operations when combined with reading data or using regular expressions. See the following examples.

This is without PEP 572:

running = True
while running:
    data = get_more_data()
    if not data:
        running...
