When should I use polymorphism in Python?

When should I use polymorphism in Python?

Polymorphism allows methods to do different things based on the object it is acting upon. You should use it when you want to define a common interface for different data types.

Can you give me an example of polymorphism in Python?

Sure! For instance, if you have a base class Animal with a method speak(), subclasses like Dog and Cat can implement speak() differently. This way, you can call speak() on any Animal object without knowing its specific type.

What are the benefits of using polymorphism?

The benefits include code reusability, easier maintenance, and the ability to extend functionality without modifying existing code.

Are there any downsides to using polymorphism?

Yes, it can introduce complexity and may lead to performance overhead if not used judiciously. It's important to balance its use with code clarity.
