Objects are instances of classes from "summary" of Python Programming by John M. Zelle
In Python, classes are used to define new types of objects. Think of a class as a blueprint or template for creating objects. When you create an object based on a class, you are said to be instantiating the class. The object you create is called an instance of the class. For example, suppose we have a class called `Car` that represents a generic car. This class might have attributes like `make`, `model`, and `year`, as well as methods like `start` and `stop`. We can create instances of the `Car` class by calling the class with the `Car()` syntax. Each instance of the `Car` class would represent a specific car with its own make, model, and year. When you create an instance of a class, you are essentially creating a new object with its own set of attributes and methods. Each instance of a class is independent of the others, meaning that changes made to one instance do not affect the others. This allows you to create multiple objects based on the same class that behave differently. Classes can also be used to organize code and data in a logical and structured way. By defining classes that represent different types of objects, you can keep related code and data together and easily reuse them in different parts of your program. This can help make your code more modular, maintainable, and easier to understand.- The concept of objects being instances of classes is fundamental to object-oriented programming in Python. It allows you to define new types of objects, create instances of those objects, and organize your code in a logical and structured way. By understanding this concept, you can take advantage of the power and flexibility of object-oriented programming in your Python programs.
