In this question, we will bake a class. Create a class Cake, with the following instance attributes:• name (a string)• ingreds (a list of strings)• price (a float)The Cake class has also the following methods:• Write a constructor that takes as input a string indicating the cake name, and a list of stringsindicating the cake ingredients. (No docstring needed.) The constructor uses these values toinitialize the attributes accordingly. Note that each cake should be assigned a random price between$10.00 (inclusive) and $15.00 (exclusive). You may import random.Moreover, a cake must contain at least three or more ingredients. If this is not the case, theconstructor should raise a ValueError. For this constructor, do not worry about making a copyof the input array. You can simply copy the reference received as input into the correspondingattribute.1• Write a method (including docstring) called _str__ which returns a string containing the name ofthe cake and its price (rounded to 2 decimal places using round). For instance, the method mightreturn the following string: 'Carrot Cake $13.75'. Note that this method should not modify thevalues stored in the attributes of the given object.Outside the class Cake, write the following two functions (including docstring):• A function called create_menu that takes as input a dictionary mapping cake names (strings) totheir list of ingredients (lists of strings). The function should use the dictionary to create and returna list of Cake objects. The function should also display the menu, one cake per line.You can decide to solve this exercise in a pair. If you do so, then you should also add thefollowing:• Inside the class Cake, write a method (including docstring) called is_better that takes another cakeas input and returns True if the current one has a better (lower) ratio between price and number ofingredients and False otherwise. For example, a $12.00 cake with 6 ingredients (i.e. with ratio 2) isconsidered to be better than a $10.00 cake with 4 ingredients (i.e. with ratio 2.5). While a $11.00cake with 4 ingredients (i.e. with ratio 2.75) is considered to be better than a $12.75885 cake with3 ingredients (i.e. with ratio 4.25295). If the ratio is the same, the method should return False.• Outside the class Cake, write a function called find_best that takes a non-empty list of cakes asinput and returns the best cake in the list. If there are ties, the function should return the bestcake which appears first in the list.

3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…

For your homework assignment, build a simple application for use by a local retail store. Your program should have the following classes: Item: Represents an item a customer might buy at the store. It should have two attributes: a String for the item description and a float for the price. This class should also override the __str__ method in a nicely formatted way. Customer: Represents a customer at the store. It should have three attributes: a String for the customer's name, a Boolean for the customer's preferred status, and a list of 5 indexes to hold Item objects. Include the following methods: make_purchase: accepts a String and a double as parameters to represent the name and price of an item this customer is purchasing. Create a new Item object with this info and append it to the internal list. If the customer is a preferred customer based on the Boolean attribute's value, take 10% off the total sale price. __str__: Override this method to print the customer's name and every…
Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.
Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }
