Am I missing something with Python not having interfaces?

 Python supports interfaces. In the example below, "Vehicle" is an
interface.

class Vehicle:
     def drive(self, count): raise Exception("I'm only an
interface... :-(")
     def number_of_wheels(self): return 0
     def fly(self): pass

class Car(Vehicle):
     def drive(self, count): print "The car walked %d steps" % count
     def number_of_wheels(self): return 4

 As you can see, there are a couple of ways you can tell others
"Vehicle" is an interface, like raising exceptions, returning useless
values or doing nothing. You could also raise an exception in
Vehicle.__init__.
