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.

Commenting Python code

Another thing to discuss is that comments in Python are marked with the # symbol. Comments are used to annotate notes or other information without having Python try to perform an operation on them. For example, the following screenshot demonstrates the use of comments when writing code. It should be noted that, normally, comments in the interactive Python prompt are not used, since it is more of a scratchpad for testing bits of code:

Python comments

You will see later on that, even though Python is a very readable language, it still helps to put comments in your code. Sometimes, it's to explicitly state what the code is doing, to explain a neat shortcut you used, or to simply remind yourself of something while you're coding, like a "to do" list.
