So long as the cat's out of the list, may as well do it "the obvious"
;-) way too:

result = set(list1) - set(list2)

Of course the result is a set then.  Maybe that will work fine in
context, maybe not.  I leave it as an exercise to figure out how to
change it back into a list (hint:  try the obvious way first ;-) ).
