Inheritance in Python

Question

We just started learning about class inheritance and attribute lookup in python. I have a question about the following code:

class a : n = 1
class b : n = 2
class c : n = 3
class d (a,b) : pass
class e (d,c) : pass

I know that e.n would equal 1 due to the nature of attribute lookup procedure (depth first search). However, how would I access, say, class c's n from class e? I've tried e.c.n, but that gives me an error. Can someone tell me what I'm doing wrong? Thanks in advance!

You can't get there from here. Class attributes are replaced. Use the class reference directly (c.n).
