This just assigns x to the last element of the list, it doesn't
process the whole list. One possibility would be to ensure that x and
y are always lists, then use nested loops to iterate over all
combinations:
x = getattr(brain, horizontal)
if not isinstance(x, list):
  x = [x]
y = getattr(brain, vertical)
if not isinstance(y, list):
  y = [y]
for first in x:
  for second in y:
    if first and second and (first, second) in table:

I don't really see this clearly as I may have n'th values for 'x' and 
n'th values for 'y' so I will need to loop over all these, but without 
knowing the n'th value where to stop my loop?

Or have I missed the point ;)


etc.
