(Invoice Class) Create a class called Invoice that a hardware store might use to representan invoice for an item sold at the store. An Invoice should include four data members—a part number (type string), a part description (type string), a quantity of the item being purchased (typeint) and a price per item (type int). Your class should have a constructor that initializes the fourdata members. A constructor that receives multiple arguments is defined with the form:ClassName( TypeName1 parameterName1, TypeName2 parameterName2, ... )Provide a set and a get function for each data member. In addition, provide a member functionnamed getInvoiceAmount that calculates the invoice amount (i.e., multiplies the quantity by theprice per item), then returns the amount as an int value. If the quantity is not positive, it should beset to 0. If the price per item is not positive, it should be set to 0. Write a test program that demonstrates class Invoice’s capabilities
Problem: Employee and ProductionWorker Classes
Write a python class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:
• Shift number (an integer, such as 1, 2, or 3)• Hourly pay rateThe workday is divided into two shifts: day and night. The shift attribute will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write the appropriate accessor and mutator methods for this class. Once you have written the class, write a program that creates an object of the ProductionWorker 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
Note: The program should be written in python.
Sample Input/Output:
Enter the name: Ahmed Al-AliEnter the ID number: 12345Enter the department:…
(Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.
