What is the difference between composition and inheritance in Python?
In Python, inheritance allows a class to inherit attributes and methods from another class, while composition involves creating classes that contain instances of other classes.
Can you give me an example of each?
Sure! For inheritance, you might have a class Animal
and a subclass Dog
that inherits from it. For composition, you could have a class Car
that contains an instance of a Engine
class.
Which one is better to use?
It depends on the situation. Inheritance is useful for establishing a clear hierarchy, while composition is often preferred for flexibility and reusability.
Are there any drawbacks to using inheritance?
Yes, inheritance can lead to tight coupling between classes and can make the code harder to maintain. Composition can help mitigate these issues.
