A library wants to manage its collection of books and authors more efficiently. They would like to create a Python program to help with this task. The following requirements need to be implemented: Create an Author class with the attributes: name, dob (date of birth), and nationality. The class should have a __str__ method to represent the author in a user-friendly format. Create a Book class with the following attributes: title, author (an instance of the Author class), publication_date, and price. Also, include a class variable all_books that keeps a list of all book instances created.The Book class should have: A __str__ method to represent the book in a user-friendly format. A __eq__ method to compare two books. Two books are considered the same if they have the same title and author. A __lt__ method to compare two books based on their publication dates. A class method get_all_books that returns a list of all books in the library. A static method most_expensive_book that takes…
In Python write an address book program using object oriented design, you would need at least two things: An “address book” class. A class that will store information about a “person”. Using knowledge of classes, and thinking constructively about the task assigned with object-oriented design in mind. Requirements: A class named `Person`. Class constructor requires first, middle and last name of your person. Class method `set_email` must exist to set the person’s e-mail address, e.g.` "kirk@starfleet.org".` Class method `get_info` that returns a string formed from a person’s first, middle, last names and e-mail address, in this exact form: `"James Tiberius Kirk <kirk@starfleet.org>".` Class method `__str__ that returns the same string as the `get_info` method. A class named `AddressBook`. It must do the following: No class constructor arguments are required, though you should consider some internal data structures for initialization. Class method…

Class name BankAccount Attributes __balance float __pin integer Methods __init_() get_pin() check_pin() deposit() withdraw() get_balance() The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). Thepin should be generated randomly when the account object is created. The initial balance shouldbe 0.get_pin()should return the pin.check_pin(pin) should check the argument against the saved pin and return True if itmatches, False if it does not.deposit(amount) should receive the amount as the argument, add the amount to the accountand return the new…
Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (p. 479). Kindle Edition. 9. Write a program named SalespersonDemo that instantiates objects using classes named RealEstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each object’s data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salesperson’s full name—the first and last names separated by a space. Then perform the following tasks: • Create two child classes of Salesperson: RealEstateSalesperson and GirlScout. The RealEstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are…

use C++ programming language. Design and implement a class dayType that implements the day of the week in a program. The class dayType should store the day, such as Sun for Sunday. The program should be able to perform the following operations on an object of type dayType: Set the day. Print the day. Return the day. Return the next day. Return the previous day. Calculate and return the day by adding certain days to the current day. For example, if the current day is Monday and we add 4 days, the day to be returned is Friday. Similarly, if today is Tuesday and we add 13 days, the day to be returned is Monday. Add the appropriate constructors.

PLEASE USE 2 CLASSES (you do not have to answer quickly please take your time) In the Game of 21, a player is dealt two cards from a deck of playing cards and then optionally givena third card. The player closest to 21 points without going over is the winner. Use object-orienteddevelopment to create a Game of 21 application that allows the user to play the Game of 21 against thecomputer. The Game of 21 application and its objects should:• Deal a card from a deck of playing cards by generating a random number between 1and 13. A 1 corresponds to an Ace, numbers 2 through 10 correspond to those cards,and 11 through 13 corresponds to Jack, Queen, and King. The Jack, Queen, and Kinghave a value of 10 in the Game of 21. An Ace can have a value of either 1 or 11.• Allow the player to stay with two cards or be given a third card.• Announce the winner.• Play rounds until the player says to stop
Pick an object around you and create a class out of it - plan your class (Name, Parameters, Functionality) - your object has to have at least 4 parameters ( 2 string, 2 numbers) - your data has to be private - implement (override) the function __str__ to show the relative information for your function - create at least one extra function in your class for the object - create 4 different objects from your design class This question is based on python.
Python Program: Write a program which controls a metro train and that keeps track of stations and who gets on and off. Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes. nextStation(int lastStation) which determines…
