not that efficient but

i,*d = 0,a,b,c
if all(d)<0:
print(yes)

Answer 6

Except all() always returns a boolean, so the check `all(iterable) < 0` will never be true. Besides, what's there to be "optimized"? The code's already readable and concise at least for a check of just three parameters long. Anyway, the correct approach with all() for your sample test would be `all(x < 0 for x in (a, b, c))`.
