Demonstration of python classes and inheritance.

pets.py

class Pet(object):
    
    def __init__(self, name, species):
        self.name = name
        self.species = species

    def getName(self):
        return self.name

    def getSpecies(self):
        return self.species

    def __str__(self):
        return "%s is a %s" % (self.name, self.species)

class Dog(Pet):
    
    def __init__(self, name, chases_cats):
        Pet.__init__(self, name, "Dog")
        self.chases_cats = chases_cats

    def chasesCats(self):
        return self.chases_cats

class Cat(Pet):
    def __init__(self, name, hates_dogs):
        Pet.__init__(self, name, "Cat")
        self.hates_dogs = hates_dogs

    def hatesDogs(self):
        return self.hates_dogs

THANKS A LOT

many thanks for your tutorial. I found it to be the best so far that explains class inheritance.

Great tutorial!

Many Thanks for this sort example :)

Really nice documentation on class inheritance

Thank you very much for the explanation. i have a question please. if i have something like this:
class Pet(object):

def __init__(self, name, specie):
    self.name = name
    self.specie = specie

def get_name(self):
    return self.name

def get_specie(self):
    return self.specie

def __str__(self):
    return '{} is a {}'.format(self.name, self.specie)

class Dog(Pet):

def __init__(self, name, color):
    Pet.__init__(self, name, 'Dog')
    self.color = color

def color(self):
    return self.color

EOF

what if i want the class Dog to print out name is a color dog inheriting from method str of class Pet. is it possible?
if yes, how? thanks
