  • Polymorphism allows a subclass to override or change a specific behavior, exhibited by the parent class
Polymorphism Example

In the below shown example, you will find

  • Improvised Employee class with two methods getSalary and getBonus.

  • Definition of ContractEmployee class derived from Employee. It overrides functionality of getSalary and getBonus methods found in it's parent class Employee.

Example


 class Employee(Person):
    all_employees = EmployeesList ()
    def __init__(self, fname, lname, empid):
        Person.__init__(self, fname, lname)
        self.empid = empid
        Employee.all_employees.append(self)
    def getSalary(self):
        return 'You get Monthly salary.'
    def getBonus(self):
        return 'You are eligible for Bonus.'
Polymoprhism Example Contd.

 class ContractEmployee(Employee):
   def getSalary(self):
        return 'You will not get Salary from Organization.'
    def getBonus(self):
        return 'You are not eligible for Bonus.'
e1 = Employee('Jack', 'simmons', 456342)
e2 = ContractEmployee('John', 'williams', 123656)
print(e1.getBonus())
print(e2.getBonus())

Output


 You are eligible for Bonus.
You are not eligible for Bonus.
