You don't need interfaces with Python. Duck typing makes that all possible.
This is perfectly valid:
class Dog(object):
def move(self):
print "Dog is moving"
class Car(object):
def move(self):
print "Car is moving"
things = [Dog(), Car()]
for thing in things:
thing.move()
Despite Dog and Car being completely different classes with no relationship
with each other, the code runs just fine.
