Part Four: Example 4: Employee Payment Platform System (EPPS)

 In this example, we are going to create a very basic template of a government employee payment system that would be used to pay three different kinds of workers. The classes we would consider in this example are mainstream government workers, university workers and oil workers.

The first class to be created would be that of the mainstream workers because it contains all the attributes common to all the three classes of workers. 

Next, we create the university class of workers which would inherit all the attributes of the mainstream workers and in addition would have the attribute ‘allowance’ which is peculiar to only this class of workers. 

Finally, we would create the oil worker class which would also inherit all attributes from the mainstream worker class but would have the peculiar attribute ‘offshore’ attributed to this class of workers only.

Below is the code to execute the Employee Payment Platform System (EPPS). 

 

print('Employee Payment Platform System (EPPS)')
print('------------------------------------------')


class Employee:
    def __init__(self, name, age, rank):
       self.name = name
       self.age = age
       self.rank = rank

    def pay(self):
        print('pay')


class University(Employee):
    def allowance(self):
        print('allowance')


class Oil(Employee):
    def offshore(self):
        print('offshore')


print('')
employee1 = Employee('Mike', 34, 'Manager')
employee1.pay()

print('')
print('--------------------')
university1 = University('Ali', 28, 'Dean')
university1.pay()
university1.allowance()

print('')
print('--------------------')
oil1 = Oil('Jay', 45, 'Supervisor')
oil1.pay()
oil1.offshore()

 

When we run the code we have the following output:

 

Employee Payment Platform System (EPPS)

------------------------------------------

 

pay

 

--------------------

pay

allowance

 

--------------------

pay

offshore

 

 From the code above, all employees have common parameters (name, age, rank) and a common method (function) ‘pay’.

However, the university class inherits all those attributes from the employee class and in addition have the peculiar method, ‘allowance’ attributed to this class only.

Similarly, the oil worker class inherits all the attributes from the employee class and in addition have the peculiar attribute ‘offshore’.

We can then add our employees based on the class they belong and they would automatically get all the payment they are entitled to.

If required, at any time, we can add, remove, modify any of the attributes in any of the classes and the changes would affect only the targeted employees.
