Book Description

Learn Python Programming, Third Edition is both a theoretical and practical introduction to Python, an extremely flexible and powerful programming language that can be applied to many disciplines. This book will make learning Python easy and give you a thorough understanding of the language. You'll learn how to write programs, build modern APIs, and work with data by using renowned Python data science libraries.

This revised edition covers the latest updates on API management, packaging applications, and testing. There is also broader coverage of context managers and an updated data science chapter.

The book empowers you to take ownership of writing your software and become independent in fetching the resources you need. You will have a clear idea of where to go and how to build on what you have learned from the book.

Through examples, the book explores a wide range of applications and concludes by building real-world Python projects based on the concepts you have learned.

What you will learn

• Get Python up and running on Windows, Mac, and Linux
• Write elegant, reusable, and efficient code in any situation
• Avoid common pitfalls like duplication, complicated design, and over-engineering
• Understand when to use the functional or object-oriented approach to programming
• Build a simple API with FastAPI and program GUI applications with Tkinter
• Get an initial overview of more complex topics such as data persistence and cryptography
• Fetch, clean, and manipulate data, making efficient use of Python's built-in data structures

Who this book is for
