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.

Strings

Strings in programming are simply text; either individual characters, words, phrases, or complete sentences. They are one of the most common elements to use when programming, at least when it comes to interacting with the user. Because they are so common, they are a native data type within Python, meaning they have many powerful capabilities built in. Unlike other languages, you don't have to worry about creating these capabilities yourself.

Strings in Python are different than in most other languages. First off, there are no char types, only single character strings (char types are single characters, separate from actual strings, used for memory conservation). Strings also can't be changed in-place; a new string object is created whenever you want to make changes to it, such as concatenation. This means you have to be aware that you are not manipulating the...
