"""
sometimes you’ll be working with a derived class (or subclass) and realize that you’ve overwritten 
a method or attribute defined in that class’ base class (also called a parent or superclass) 
that you actually need. Have no fear! You can directly access the attributes or methods of a 
superclass with Python’s built-in super call.

The syntax looks like this:

class Derived(Base):
  def m(self):
    return super(Derived, self).m()

Where m() is a method from the base class.

By defining a method with the same name as found in the base class, Employee, 
we are overriding the functionality so that any PartTimeEmployees will have their wages calculated appropriately.
