- Lab 2 – Designing a class This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab. Design a class named Computer that holds the make, model, and amount of memory of a computer. Include methods to set the values for each data field, and include a method that displays all the values for each field. For the programming problem, create the pseudocode that defines the class and enter it below. Enter pseudocode herearrow_forwardclass Product: def __init__(self, product_id, name, price, quantity): self.product_id = product_id self.name = name self.price = round(price, 2) self.quantity = quantity def get_product_description(self): return (f"Product ID: {self.product_id}, " f"Name: {self.name}, " f"Price: ${self.price:.2f}, " f"Quantity Available: {self.quantity}") class ElectronicProduct(Product): def __init__(self, product_id, name, price, quantity,warranty_period): self.warranty_period = warranty_period super().__init__(product_id,name,price,quantity) def get_product_description(self): base_description = super().get_product_description() return base_description + f"\nWarranty: {self.warranty_period}" class ClothingProduct(Product): def __init__(self, product_id, name, price, quantity,size): self.size = size…arrow_forward2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.arrow_forward

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…arrow_forward
