Some syntax, code with output
To demonstrate the practical application of Python classes, let’s consider a simple example.
We will create a class called “Car” that has attributes such as “make” and “model”. We will also define a method within the class to display information about the car.
“`python class Car: def __init__(self, make, model): self.make = make self.model = model
def display_info(self): print(f”This car is a {self.make} {self.model}”) “`
Now, let’s create an instance of the Car class and call the display_info method to see the output.
“`python my_car = Car(“Toyota”, “Corolla”) my_car.display_info() “`
When you run this code, the output will be: “` This car is a Toyota Corolla “`
This example illustrates how classes can encapsulate data and behavior into objects, making it easier to manage and manipulate related information. By defining classes and creating instances of those classes, you can organize your code more efficiently and improve its readability and maintainability.
