Explanation

- **Composition** is an OOP principle where one object is made up of other objects, i.e., it has instances of other classes as attributes. Composition represents a "has-a" relationship between objects.
- **Has-A Relationship**: This means that an object can contain other objects, which may represent part of its functionality.

Steps

• Define classes for both the containing class and the contained class.
• Create an instance of the contained class as an attribute in the containing class.
• Use the contained object’s methods or attributes from the containing class.

class Engine:
    def start(self):
        print("Engine started.")
 
class Car:
    def __init__(self, brand):
        self.brand = brand
        self.engine = Engine()  # Car has an engine (Composition)
 
    def drive(self):
        self.engine.start()
        print(f"The {self.brand} is driving.")
 
car = Car("Toyota")
car.drive()
