Find the difference between two sets, namely ${-\frac{19}{7}, 0, -2, 5 \sqrt{2}, -3 \sqrt{2}} \setminus {-\frac{19}{7}, 3 \sqrt{5}, -3 \sqrt{5}, -3 \sqrt{2}}$.

import math

fst = set((-(19/7), 0, -2, 5*math.sqrt(2), -3*math.sqrt(2),))
snd = set((-(19/7), 3*math.sqrt(5), -3*math.sqrt(5), -3*math.sqrt(2),))
print(fst - snd)
