Learning Python Application Development

By: Ninad Sathaye

Overview of this book

Python is one of the most widely used dynamic programming languages, supported by a rich set of libraries and frameworks that enable rapid development. But fast paced development often comes with its own baggage that could bring down the quality, performance, and extensibility of an application. This book will show you ways to handle such problems and write better Python applications. From the basics of simple command-line applications, develop your skills all the way to designing efficient and advanced Python apps. Guided by a light-hearted fantasy learning theme, overcome the real-world problems of complex Python development with practical solutions. Beginning with a focus on robustness, packaging, and releasing application code, you’ll move on to focus on improving application lifetime by making code extensible, reusable, and readable. Get to grips with Python refactoring, design patterns and best practices. Techniques to identify the bottlenecks and improve performance are covered in a series of chapters devoted to performance, before closing with a look at developing Python GUIs.

Testing GUI applications


In a complex and feature-rich GUI application, the user is presented with many choices of widgets, menus, keyboard shortcuts, and so on. As seen earlier in the chapter, the event-driven nature of GUI programs lets the user dictate the program flow. This often presents many possible ways for the user to perform certain operations to arrive at the desired output.

Tip

It should be noted that we are not going to write any code here. This is just a high-level discussion that touches upon a few important testing considerations. For further learning on this topic, start with the following wiki page: https://en.wikipedia.org/wiki/Graphical_user_interface_testing.

Imagine a GUI application that allows selecting some object in the application window, for example, a folder icon on the desktop. The user can hover the mouse over the icon to highlight that object, and then click on it to select it. Alternatively, he can do a window selection, where a selection window is drawn around...
