1. Make a Friend class with a_str_ method so we can view their favorite foods and their height. Your Friend class should initially be the same as it was in hw6. It needs an _init__ method, same as in hw6, and an add_favorite_foods method, same as in hw6. Additionally, we will add a _str_ method that displays the friend's name, height and favorite foods. Their favorite foods should be displayed in sorted alphabetical order (default sorting order is fine, don't worry about case), separated by commas. The appropriate formatting is shown in the example below. >> friend1 = Friend ("sarah", 165) >> friend1.add_favorite_food ("strawberries") >> friend1.add_favorite_food("apple pie") >> str(friend1) '[FRIEND name: sarah, height: 165, favorite foods: apple pie, strawberries]*

Add three methods to the Student class that compare twoStudent objects. One method (__eq__) should test for equality. A second method (__lt__) should test for less than. The third method (__ge__) should test for greater than or equal to. In each case, the method returns the result of the comparison of the two students’ names. Include a main function that tests all of the comparison operators. Note: The program should output in the following format: False: False True: True True: True False: False True: True True: True True: True True: True True: True True: True code: class Student(object): """Represents a student.""" def __init__(self, name, number): """All scores are initially 0.""" self.name = name self.scores = [] for count in range(number): self.scores.append(0) def getName(self): """Returns the student's name.""" return self.name def setScore(self, i, score): """Resets the ith score, counting…
An artist's discography includes several albums. Each album includes several songs. We want to model the Discography, Album and Song classes as follows • a discography has a single artist attribute and a total_time method that returns the total minutes corresponding to the artist's entire discography • an album has a single name attribute and a total_time method that returns the total minutes for the songs on the album a song has two attributes: title and duration and a duration method that returns the duration in minutes of the song • we want to take advantage of the composite pattern so that the duration method delivers the total number of minutes of a song, album or the entire discography of the artist depending on the object in question a) Draw a UML class diagram showing the solution b) Write the Ruby code that implements it
project-8c Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. 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. The function should return the resulting dictionary. For example, it could be used like this: emp_names =…

Add a list of procedures in your patient class, fill them and print them with the patient data. This is called composition which is a "has a" relationship. A patient has procedures. Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator…
1. Create a class called Plant with the data member plant name and color. 2. Create a child class called Tree with data member tree name, tree number and color. Inherit all the properties and behaviors from the base class to the child class. 3. Find the total number of times, character ‘a’ available in the plant name and tree name and display the method name as compare. 4. Use display method in both the classes to display“I am Plant” in parent class, and “I am Tree” in child class with all inputs needs to be displayed. Note: Get all the inputs through scanner class.
Create a class called Employee that contains two attributes: name and number. Next, write a class named Production Worker that is a subclass of the Employee class. The Production Worker class should add extra attributes called shift_number (an integer, either 1 or 2) and pay_rate. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the Employee class and an object of the Production Worker class and prompts the user to enter data for each of the object's data attributes. Store the data in the object, then use the object's accessor methods to retrieve it and display it on the screen.
Write a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. In other words, write methods so you can set the attribute values or get their values. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute. Next, write a program that creates an instance of the…
In Assignment 4, you created a Card class that represents a standard playing card. Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class using an array. Include methods to shuffle the deck, deal a card, return the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck. Document your design with a UML Class diagram. Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt along with the number of cards left in the deck. Hint: The constructor for DeckOfCards should have nested for loops for the face values (1 to 13) within the suit values (1 to 4) calling the two parameter constructor. The shuffle method does not have to simulate how a deck is physically shuffled; you can achieve the same effect by repeatedly swapping pairs of…

Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230
Create a class called Student that includes a data member that holds a name for each object created from the class and a data member that represents the number of students. That is, the first object created will be 1, the second 2, and so on.To do this, you’ll need another data member that records a count of how many objects have been created so far. (What keyword specifies this?) Then, as each object is created, its constructor increase the count member variable by one.Then write a main() program that creates three objects and queries each one about their names and the count.
