python extending class

Sometimes we need to extend an existing class, lets do it some python way

#speak.py
class Speak(object):
    def __init__(self,tone):
        self.tone = tone
    def getTone(self):
        print self.tone

#anyName.py
from speak import Speak

class Bird(Speak):
    def __init__(self,birdTone):
        #construct super class
        Speak.__init__(self,birdTone)


class Cow(Speak):
    def __init__(self,cowTone):
        #another way to construct super class
        super(Cow, self).__init__(cowTone)
       

bird= Bird("Bird Talk")
bird.getTone()

cow= Cow("Cow Talk")
cow.getTone()

Output:

Bird Talk
Cow Talk
