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.

Graphical frameworks

There are a number of GUI frameworks available nowadays. Since we are using Python, we will look at Python-specific frameworks:

  • Tkinter: This is actually a Python binding for the Tk GUI toolkit. It is considered to be the standard Python GUI framework that is available on all OS installations of Python. For a long time, the widgets included in Tkinter didn't use the OS-scheme, so Tkinter applications looked out of place. That has been fixed in the
    latest versions, so now Tkinter programs look like native applications.
  • wxPython: This uses a Python wrapper for the cross-platform wxWidgets toolkit. There was a time when it was considered as the replacement for the built-in Tkinter framework, but that hasn't happened. The main code is compatible with Python 2.x, while the Phoenix Project was designed to create a Python 3.x-compatible version from the...
