Answer 1

class Employee(object):
    def getdata(self):
        self.emp_no = input("Enter employee number: ")
        self.name = input("Enter employee name: ")

    def printdata(self):
        print("Employee number:", self.emp_no)
        print("Name:", self.name)

class Payroll(Employee):
    def inputdata(self):
        self.getdata()
        self.salary = float(input("Enter salary: "))

    def outdata(self):
        self.printdata()
        print("Salary:", self.salary)

class Leave(Payroll):
    def acceptdata(self):
        self.inputdata()
        self.no_of_days = int(input("Enter number of leave days: "))

    def showdata(self):
        self.outdata()
        print("Number of leave days:", self.no_of_days)

obj = Leave()
obj.acceptdata()
obj.showdata()
