1. We learned how to build the first class "Students" in our class. Using it as an example, create another class named "Company" containing 5 variables: fname, Iname, pay, raise rate, num of employees and 2 class methods: fullname(), apply raise(). a. Try to create this class using all the above variables and methods. Set the default raise rate to 1.04. b. Create one instance "John Smith" with salary $50000 and the default raise rate, and another instance "Bruce Lee" with salary $60000 and new raise rate to 1.10. c. Create two new methods called display_old() to print out the old salary, and another method called display_new() to print out the new salary. Apply the apply raise() method respectively to both instances to calculate salaries. d. Result should be: The former salary for John Smith is 50000 The new salary for John Smith is 52000 The former salary for Bruce Lee is 60000 The new salary for Bruce Lee is 66000 e. Answer the Question in comment: can you combine these two methods display old() and display new() to only one method display() to print out the same result? If so, rewrite your code; if not, give the reasons.

PLEASE USE PYTHON PROGRAMMING Create a class called Numbers, which has a single class attribute called MULTIPLIER, and a constructor which takes the parameters x and y (these should all be numbers). Write a method called add which returns the sum of the attributes x and y. Write a class method called multiply, which takes a single number parameter aand returns the product of a and MULTIPLIER. Write a static method called subtract, which takes two number parameters, b and c, and returns b - c. Write a method called value which returns a tuple containing the values of x and y.

Help, I making a elevator simulator, I need help in writing code in the Elevator class and it's polymorphism class. I am not sure what to do next. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators.

Python:Please read the following. The Game class The Game class brings together an instance of the GameBoard class, a list of Player objects who are playing the game, and an integer variable “n” indicating how many tokens must be aligned to win (as in the name “Connect N”). The game class has a constructor and two additional methods. The most complicated of these, play, is provided for you and should not be modified. However, you must implement the constructor and the add_player method. __init__(self,n,height,width) The Game constructor needs to initialize three instance variables. The first, self.n, simply holds the integer value “n” provided as a parameter. The second, self.board, should be a new instance of the GameBoard class (described below), built using the provided height and width as dimensions. The third, self.players, should be an initially empty list. add_player(self,name,symbol) The add_player method is provided a name string and a symbol string. These two values should be…
Program - Python Make a class.The most important thing is to write a simple class, create TWO different instances, and then be able to do something. For example, create a pizza instance for Suzie, ask her for the toppings from the choices, and store her pizza order. Then create a second pizza instance for Larry, ask for his toppings and store his pizza order. Then print both of their orders back out. You do not need to make your class very complicated. (Shouldn't be the pizza example but something similar)

Write in python language thank you
In Python Please use docstrings and comments for better explanation. Thanks
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

Apologize for the miscommunication, The language is in Python Create a simple empty Vehicle class. Update the Vehicle class with two instance variables maximum speed and mileage of the car. Create a class variable of the manufacturer and initialize all class and instance variables. different objects among them two are from one manufacturer and the remaining two are from another manufacturer. Write two methods in the class Vehicle, one for displaying the seating capacity of the vehicle and another one is for calculating fuel used by the car by the equation: Maximum Distance Covered / Mileage of the car. and Display the result from the method. Create two children from the Vehicle class: Bus and Car. Both the child classes will inherit all the variables and methods of the Vehicle class. The car class will modify the members of the parent class in their own way and display it from its class object. Bus will be inherited to another class called MiniBus. Create a new method in…
