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…

Create a class named Student that has fields for an ID

You need a way to prevent class fields from being corrupted by mistake.

Describe the class's private and public components.

in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…

Design a class in python named Book that holds a stock number, author, title, price, and number of pages. Include methods to set and get the values for each data field. Also include a displayInfo() method that displays each of the Book's data fields with explanations.Design a class named TextBook that is a child class of Book. Include a new data field for the grade level of the book. Override the Book class displayInfo() method to accommodate the new grade-level field.
