Question

Using Inheritance

Consider the following (base) class.

class Employee(object):
   def __init__(self, name, salary):
       self._name = name
       self._salary = salary

   def my_name(self):
       return self._name

   def wage(self):
       return self._salary/26   # fortnight pay

Define a new subclass of Employee called Worker. A worker has a manager, who is another employee; their manager is given as an argument to the constructor.

You should define a method get_manager that returns the worker’s manager.

    boss = Employee('Mr. Burns', 1000000)
    worker = Worker('Waylon Smithers', 2500, boss)

Define another subclass of Employee called Executive. An executive has a yearly bonus in addition to a wage.

Override the Employee.wage method in order to take the bonus into account. You must call Employee.wage from Executive.wage (using super). Remember that the existing wage method calculates a fortnightly pay, but the bonus is annual.

    executive = Executive('Joseph Bloggs', 25000, 10000)

class Employee(object):
"""
A salaried employee.

"""
def __init__(self, name, salary):
"""
Initialise a new Employee instance.

Parameters:
name (str): The employee's name.
salary (float): The employee's annual salary.

"""
self._name = name
self._salary = salary

def get_name(self):
"""
(str) Return the name.

"""
return self._name

def wage(self):
"""
(float) Return the forgnightly wage.

"""
return self._salary/26
