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.

When designing a GUI, it is common to sketch out what the final interface should look like. This is known as wireframing. While there are applications designed explicitly for wireframing, even something as simple as MS PowerPoint can be used.

Ideally, we would talk to the end users and figure out what they wanted in a GUI, allowing them to test each version of the software until we found the best solution. However, when it comes to a Human-Machine Interface (HMI), as GUIs for industrial applications are commonly called, the interface is pretty much dictated by the system being used.

HMIs have to show what the system looks like, much like a schematic diagram, as well as telling the operator the current system parameters and conditions. The following screenshot shows a representative example of an HMI for an industrial application:

Frequently, the HMI allows...
