Python: Simple example of class inheritance

Class Inheritance 01| .py

import sys

class Animal:
   def __init__(self):
      print "Animal created"

   def whoAmI(self):
      print "Animal"

   def eat(self):
      print "Eating"


class Dog(Animal):
   def __init__(self):
      Animal.__init__(self)
      print "Dog created"

   def whoAmI(self):
      print "Dog"

   def bark(self):
      print "Woof!"


d = Dog()
d.whoAmI()
d.eat()
d.bark()

Class Inheritance 02 | .py

class Person:

    def __init__(self, first, last):
        self.firstname = first
        self.lastname = last

    def Name(self):
        return self.firstname + " " + self.lastname

class Employee(Person):

    def __init__(self, first, last, staffnum):
        Person.__init__(self,first, last)
        self.staffnumber = staffnum

    def GetEmployee(self):
        return self.Name() + ", " +  self.staffnumber

x = Person("Marge", "Simpson")
y = Employee("Homer", "Simpson", "1007")

print(x.Name())
print(y.GetEmployee())
