Develop an object-oriented Python Pig(dice game) using test-driven development process. The Pig(dice game) should be played by one player towards the computer and as a two player game.
You application should be divided into classes where each class resides in its own file. Some suggestions of classes are Game, Dice, DiceHand, Histogram, Intelligence, HighScore, Player
- Each player should be able to select a name for them self and a player should be able to change their name.
- There should be a persistent high score list where statistics on each player and their played games, are stored and visible. The statistics should remain if the player changes their name.
- One should be able to see the rules of the game.
- One should be able to play a whole game round. One should be able to quit the current game and restart it.
- There should be a cheat which one can use for testing purpose and reach the end of the game faster. This cheat should contain a information text some one knows how to…
IN Python
Create a class called Student that has the following attributes:• __first_name• __last_name• __final_scoreThe class should have following methods:• letter_grade: calculates the letter grade based on final• display_student_info: displays student informationWrite a Python program that creates at least five objects based on Student class. Use display_student_info method to print each object’s information as output including letter grade. Please modify the class if you think letter_grade needs to be stored as well for a class object

Each row contains item ID,manufacturer name, item type, and optionally a damaged indicatorb) PriceList.csv -- contains items listed by row. Each row contains item ID and the item price.c) ServiceDatesList.csv – contains items listed by row. Each row contains item ID and servicedate. Required Output:1) Interactive Inventory Query Capabilitya. Query the user of an item by asking for manufacturer and item type with a single query. i.

Constructors – create at least 2 constructors No parameter With parametersSet id and name using the constructor with parameters. 3. Methods toString method : To print the details of the Student.

Write some test cases in main methodarrow_forwardMust be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…arrow_forwardPLEASE CODE IN PYTHON PLEASE USE CLASSES 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 correspond 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.arrow_forward

Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method.

Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object.
