OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- 1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2.

- Write a class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than threeGiven the provided class, please make the following modifications. class Employee: def __init__(self, name, number): self.name = name self.number = number class ProductionWorker(Employee): def __init__(self, name, number, shift_number, employee_number): Employee.__init__(self, name, number) self.shift_number = shift_number self.employee_number = employee_number # Create an instance of the ProductionWorker class and test itemployee1 = ProductionWorker("John Doe", 1234, 2, 5678)print(employee1.name)print(employee1.number)print(employee1.shift_number)print(employee1.employee_number) Write a class 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.
