# python tutorial day 57: classes and objects
in this tutorial, we will explore the concepts of classes and objects in python, which are fundamental to object-oriented programming (oop). we'll understand how to create classes, instantiate objects, and utilize methods and attributes.
what are classes and objects?
- **class**: a class is a blueprint for creating objects. it defines a set of attributes and methods that the created objects will have. think of a class as a template.
- **object**: an object is an instance of a class. it is created based on the class definition and can hold specific data and functionality.
creating a class
to define a class in python, we use the `class` keyword followed by the class name. by convention, class names are written in camelcase.
syntax:
example:
let's create a simple class named `car`.
explanation:
- **`__init__` method**: this is the constructor method that initializes the object’s attributes when a new object is created.
- **`self`**: a reference to the current instance of the class. it's used to access variables that belong to the class.
creating objects
now that we have defined a class, we can create objects (instances) of that class.
example:
explanation:
- we create two objects, `car1` and `car2`, by calling the `car` class and passing the required parameters.
- we then call the `display_info` method for each object to print their details.
class attributes vs instance attributes
- **class attributes**: shared by all instances of a class. in our `car` class, `wheels` is a class attribute.
- **instance attributes**: unique to each instance. `make`, `model`, and `year` are instance attributes.
example of class attributes:
modifying attributes
you can modify instance attributes after creating an object.
example:
inheritance
inheritance allows a class to inherit attributes and methods from another class. this promotes code reusability.
