Try printing self.topics. It should always be a list of topics.
Ah, yes, that made me find a bug when I was creating the Expert objects:
the lists of known topics were not created properly. I should have
posted more code I suppose! Thanks for the help, this problem has now
been s

Your problem is here.
self.topics is a list of topic instances: but you're calling str() on the
list itself to turn the LIST itself into a string. Compare:
>>> x = [1,2,3]
>>> x
[1, 2, 3]
>>> str(x)
'[1, 2, 3]'
Now, after str(se

You're turning your list into a string -- try this:

Hello, I've written two classes. One class describes experts: experts
has a unique ID and a name. An expert knows topics and other experts. A
