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.

There are a lot of tests that can be performed. The test file for this model,, currently holds more than 500 lines of code, so I won't be covering it here; however, it will be included in the book's code repository for you to examine at your leisure.

I do want to mention that, quite often (in my experience), testing failures aren't indicative of a problem with the code being tested, but with the tests themselves. For example, look at the following figure:

Fuel testing errors

In this test, two errors are generated. Are they related? Perhaps; a single issue can cause multiple errors, so by fixing and correcting the single issue, multiple errors can be resolved.

In this case, the error being generated in test_gate5_tank2() tells us that the expected value (39085.73879782904) does not equal the real value (19542.86939891452). As noted...
