How do I implement duck typing in Python?

Duck typing in Python means that the type or class of an object is less important than the methods it defines. You can implement it by simply using an object as long as it has the required methods.

Can you give me an example of duck typing in action?

Sure! Here's a simple example:

class Duck:
    def quack(self):
        return "Quack!"

class Dog:
    def quack(self):
        return "Woof!"

def make_it_quack(animal):
    print(animal.quack())

make_it_quack(Duck())  # Outputs: Quack!
make_it_quack(Dog())   # Outputs: Woof!

What are the advantages of using duck typing?

Duck typing allows for more flexible and reusable code. It enables polymorphism, meaning you can use different types of objects interchangeably as long as they implement the required methods.

Are there any downsides to duck typing?

Yes, one downside is that it can lead to runtime errors if an object doesn't have the expected methods, making debugging more challenging.
