38. Classes and objects in Python
The chapter introduces the fundamental concepts of classes and objects in Python, emphasizing how classes serve as blueprints for creating objects with specified attributes and methods. It covers essential elements such as the self parameter, constructors, and the significance of defining internal data representations using methods like translate and o_distance. Various implementations for managing point coordinates highlight the flexibility and extensibility of Python's object-oriented programming features.

What we have learnt
- Classes are templates defining internal data and functions in Python.
- The self parameter refers to the instance of the class within its methods.
- Attributes and methods can be used to manipulate and represent data, such as in class representations of points.
Key Concepts
- -- Class
- A template in object-oriented programming that defines the properties and behaviors of an object.
- -- Object
- An instance of a class that contains attributes and methods defined by the class.
- -- self
- A conventional name for the first parameter of instance methods in a class, allowing access to the instance's attributes and methods.
- -- Constructor (__init__)
- A special method used to initialize new objects of a class, setting up initial attribute values.
- -- Method
- A function defined within a class that typically operates on the object's data.
