Find the difference between two sets, namely ${-4, -7, -4 \sqrt{2}, 9, -2 \sqrt{3}, -5.87, 8, \frac{19}{3}} \setminus {-5.87, -7, 1, \frac{19}{3}, \frac{1}{3}, -2 \sqrt{3}, -8}$.

import math

fst = set((-4, -7, -4*math.sqrt(2), 9, -2*math.sqrt(3), -5.87, 8, (19/3),))
snd = set((-5.87, -7, 1, (19/3), (1/3), -2*math.sqrt(3), -8,))
print(fst - snd)
