A constructor is automatically called when an object is _________.
A. Car Class
Create a Python Program where you write a class
named Car that has the following data attributes:
• _ _year_model (for the car's year model)
• __make (for the make of the car)
• _ _speed (for the car's current speed)
The Car class should have an _init_ method that
accepts the car's year model and make as arguments.
These values should be assigned to the object's
_year_model and
make data attributes. It should
also assign 0 to the __speed data attribute.
The class should also have the following methods:
accelerate()
The accelerate method should add 5 to the speed data
attribute each time it is called.
brake()
The brake method should subtract 5 from the speed
data attribute each time it is called.
• get_speed()
The get_speed method should return the current speed.
Next, design a program that creates a Car object then
calls the accelerate method five times. After each call
to the accelerate method, get the current speed of the
car and display it. Then call the brake method…
In Python: Write a class named Pet, which should have the following data attributes:
_ _name (for the name of a pet)
_ _animal_type (for the type of animal that a pet is. Example values are 'Dog','Cat', and 'Bird')
_ _age (for the pets age)
The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods:
set_nameThis method assigns a value to the _ _name field
set_animal_typeThis method assigns a value to the _ _animal_type field
set_ageThis method assignsa value to the _ _age field
get_nameThis method assignsa value to the _ _name field
get_animal_typeThis method assignsa value to the _ _animal_type field
get_ageThis method assignsa value to the _ _age field
Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type and age of his or her pet. This data should be stored as the objects attributes. Use the objects accessor methods to retrieve the pets…
