Please use your own code and please also commentary to explain what the program does for a better understanding. Thank you
![python
create a python class called Animal that define two attributes Type and Age and the following methods:
_init__ initializes the attributes Age which is mandatory, and Type which is optional when the
instanciation of an object of type animal.
Methods set_type and set_age to assign value to type and age, respectively.
Methods get_type and get_age to return the value of type and age, respectively.
Create a class called Felin class that inherits the class parent Animal. It redefines the method __init__
reusing the _init__ method of Animal, and also starting the speed attribute.
Define the methods set_speed and get_speed to assign/return the value of the speed.
Set the method _str__ to display the object of type Felin as shown in the example.
--
Define the method comparespeed of the class Felin. This method displays the fastest of two
cats. comparespeed can use any method of the class Felin or of the parent class Animal but it cannot
manipulate any attributes directly such as self.age, or self.type, or self.speed.
Example:
>>> f1 = Felin(4)
>>> f1.set_type("Lion")
>>> f1.set_vitesse(20)
>>> print(f1)
Felin:Lion - 4 - 20km/h
>>> f2 = Felin(5)
>>> f2.set_type("Jaguar")
>>> f2.set_vitesse(10)
>>> print(f2)
Felin:Jaguar - 5 - 10km/h
>>> f1.compareRapidite(f2)
the fastest cat is: Felin:Lion - 4 - 20km/h](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdb039aed-b356-40cc-ba3e-936586ecb4b2%2F725248fd-ecd2-4cab-814d-c7c36ffe540d%2Fh99aobr_processed.png&w=3840&q=75)
