Here is how I would rewrite your example:
class Shape(object):
def __init__(self, x=0, y=0):
self.x = x
self.y = y
@property
def location(self):
return (self.x, self.y)
@location.setter
def location(self, val):

Actually, in python it does make sense, with a caveat that you have

Ok, thanks for the info.
What would be a better way to do this? What I'm trying to do is treat
things in a reasonable OOP manner (all fairly new to me, esp. in
Python). Here's a made-up example with a little more context. Let's
say you're making a drawing program that can draw various shapes.

Why doesn't this work:
class C1:
def f1(self):
print("f1")
class C2(C1):
f1()
It throws this error:
Traceback (most recent call last):
File "./c1.py", line 7, in
