This is the same thing that I think you want to do.  Also, you never
increment the start variable so it always remains the same (i.e.
dictionary will only have one key), and the f6 dictionary will only
contain the last test anyway since you create a new dictionary on each
pass instead of adding to an existing dictionary.  Don't know if that
is intentional or not.
set_f4 = set(f4.keys())
set_f5 = set(f5.keys())
print set_f4.difference(set_f5)
