Look inside
In this liveProject, you’ll take on the task of extending a pricing application. You’ve just hit your first speed bump of needing to add functionality to the class that manages prices. However, that class is used elsewhere and you can’t get permission to change it. Your challenge is to implement a “monkey patch”—adding methods to the class at runtime—by experimenting with Python-bound methods.
This project is designed for learning purposes and is not a complete, production-ready application or solution.
