conn_request, weights = zip(*[
((conn, request), request[2])
for conn in unchoked_conns

Generates:
for conn in unchoked_conns
ValueError: need more than 0 values to unpack
I cannot work out what I'm doing wrong. I think it has some thing to do with the dependence of request
on conn
?

Your LC produces an empty list. Try verifying that unchoked_conns
has any elements.
zipping an empty list returns a single empty list, hence the assignment fails. That is consistent with the zip help, which clearly says:
The returned list is truncated in length to the length of the shortest argument sequence
In your case, the shortest argument sequence has length 0.
