I would have thought this would be correct, but in this case, plus in
others im playin with, I get this issue:
-----------------------
given animal.py is:
class creature:
def __init__(self):
self.noise=""
def voice(self):
return "voice:" + self.noise
class dog(creature):
def __init__(self):
self.noise="bark"
then I get this outcome...
>>>import animal
>>> beagle=animal.dog
>>> beagle.voice()
Traceback (most recent call last):
File "<input>", line 1, in ?
TypeError: unbound method voice() must be called with dog instance as
first argument (got nothing instead)
>>>
------------------------
So I guess it wants something in position of self?
any idea what Im doing wrong? - this would be very handy as its a point
Im stymied on a couple of 'projects'
thanks
