Learning Python Application Development

Summary

In this chapter, we touched upon some introductory concepts in Python to develop a simple command-line application. We first equipped ourselves by setting up a Python development environment.

The proposed introduction of more features to the application made us rethink the design. We learned how to transform the code into an object-oriented design and implemented a few of these new features.
