→ Declare the derived class salary with basic pay, DA, HRA, Gross pay, PF, Income tax and Net pay.

→ Declare and define the function getdata1() to call getdata() and get the basic pay,

→ Define the function calculate() to find the net pay

→ Define the function display() to call putdata() and display salary details .

→ Create the derived class object.

→ Read the number of employees.

→ Call the function getdata1() and calculate() to each employees.

→ Call the display() function.

Answer 1

class Employee(object):
    def getdata(self):
        self.number = input("Employee number: ")
        self.name = input("Name: ")
        self.designation = input("Designation: ")
        self.address = input("Address: ")
        self.phone = input("Phone number: ")

    def putdata(self):
        print("\nEmployee number:", self.number)
        print("Name:", self.name)
        print("Designation:", self.designation)
        print("Address:", self.address)
        print("Phone:", self.phone)

class Salary(Employee):
    def getdata1(self):
        self.getdata()
        self.basic_pay = float(input("Basic pay: "))

    def calculate(self):
        self.da = self.basic_pay * 0.20
        self.hra = self.basic_pay * 0.10
        self.gross_pay = self.basic_pay + self.da + self.hra
        self.pf = self.basic_pay * 0.12
        self.income_tax = self.gross_pay * 0.05
        self.net_pay = self.gross_pay - self.pf - self.income_tax

    def display(self):
        self.putdata()
        print("Basic pay:", self.basic_pay)
        print("DA:", self.da)
        print("HRA:", self.hra)
        print("Gross pay:", self.gross_pay)
        print("PF:", self.pf)
        print("Income tax:", self.income_tax)
        print("Net pay:", self.net_pay)

n = int(input("Enter number of employees: "))
for i in range(n):
    print("\nEmployee", i + 1)
    emp = Salary()
    emp.getdata1()
    emp.calculate()
    emp.display()

The percentage rates used in calculate() may be changed according to the organisation's rules.
