Learn Programming in Python with Cody Jackson

By: Cody Jackson

Overview of this book

Python is a cross-platform language used by organizations such as Google and NASA. It lets you work quickly and efficiently, allowing you to concentrate on your work rather than the language. Based on his personal experiences when learning to program, Learn Programming in Python with Cody Jackson provides a hands-on introduction to computer programming utilizing one of the most readable programming languages–Python. It aims to educate readers regarding software development as well as help experienced developers become familiar with the Python language, utilizing real-world lessons to help readers understand programming concepts quickly and easily. The book starts with the basics of programming, and describes Python syntax while developing the skills to make complete programs. In the first part of the book, readers will be going through all the concepts with short and easy-to-understand code samples that will prepare them for the comprehensive application built in parts 2 and 3. The second part of the book will explore topics such as application requirements, building the application, testing, and documentation. It is here that you will get a solid understanding of building an end-to-end application in Python. The next part will show you how to complete your applications by converting text-based simulation into an interactive, graphical user interface, using a desktop GUI framework. After reading the book, you will be confident in developing a complete application in Python, from program design to documentation to deployment.

Refactoring code

When debugging, testing, and troubleshooting, code is often rewritten to change how it works, a process that is also known as refactoring. The benefit of having test cases available means that changes to the code can be checked to see whether functionality has been compromised, such as interactions between functions or methods or if end-user complications have developed.

In large testing projects, continuous integration test suites are utilized to check code as the developers upload it to the server. These tests not only check each developer's code, but also check it against other code that was submitted to ensure that the entire project continues to function properly.

Refactoring can take many different forms, such as the following:

  • Adding comments to help clarify key bits of code or why a certain piece of logic was used.
  • Improving readability by separating...
