Question

Python

Define a class called Animal that abstracts animals and supports three methods:

• setSpecies(species): Sets the species of the animal object to species.
• setLanguage(language): Sets the language of the animal object to language.
• speak(): Prints a message from the animal as shown below.

The class must support supports a two, one, or no input argument constructor.

Then define Bird as a subclass of Animal and change the behavior of method speak() in class Bird.

>>> snoopy = Animal('dog', 'bark')

>>> snoopy.speak()

I am a dog and I bark.

>>> tweety = Animal('canary')

>>> tweety.speak()

I am a canary and I make sounds.

>>> animal = Animal()

>>> animal.speak()

I am a animal and I make sounds.

>>> daffy = Bird()

>>> daffy.speak()

quack! quack! quack!
