I want to initiate and calculate volume from TwoDim class without repeat to define length and wide, and without to make instance of TwoDim but direct create ThreeDim.



class TwoDim():
def __init__(self, length, width):
self.length = length
self.width = width
self.square = self.length * self.width

class ThreeDim(TwoDim):
def __init__(self, height):
self.height = height
self.volume = self.square * self.height



I try someting like this, but still not work..



class TwoDim(): 
def __init__(self, length, width):
self.length = length
self.width = width
self.square = self.length * self.width

class ThreeDim(TwoDim):
def __init__(self, length, width, height):
super().__init__(self, length, width, height)
self.height = height
self.volume = self.square * self.height

block = ThreeDim(length = 10, width = 5, height = 4)

Python 3 :



class ThreeDim(TwoDim):
def __init__(self, length, width, height):
super().__init__(length, width)
self.height = height
self.volume = self.square * self.height


Python 2 :



class ThreeDim(TwoDim, object):
def __init__(self, length, width, height):
super(ThreeDim, self).__init__(length, width)
self.height = height
self.volume = self.square * self.height


Or :



class TwoDim(object):
def __init__(self, length, width):
self.length = length
self.width = width
self.square = self.length * self.width

class ThreeDim(TwoDim):
def __init__(self, length, width, height):
super(ThreeDim, self).__init__(length, width)
self.height = height
self.volume = self.square * self.height


(classes need to inherit from object to use super() and that's one of the reason why python3 syntax is easier.)



Don't forget the self parameter on TwoDim :



class TwoDim():
def __init__(self, length, width):
self.length = length
self.width = width
self.square = self.length * self.width
