Properties in Detail
Explore the use of Python’s property() function to control attribute access in object-oriented programming. Understand how to define getters, setters, and optional deleters for attributes, and how to include documentation for properties. This lesson helps you implement clean, maintainable access to internal state in Python classes.
We'll cover the following...
