Find the union of the following sets, namely ${0, -4, \sqrt{5}, -\frac{31}{4}, 7, -10, -1.795} \cup {-7, 7, -\frac{15}{2}, 4, -1.795, -2 \sqrt{5}, -4, 3, \sqrt{5}}$.

import math

fst = set((0, -4, math.sqrt(5), -(31/4), 7, -10, -1.795,))
snd = set((-7, 7, -(15/2), 4, -1.795, -2*math.sqrt(5), -4, 3, math.sqrt(5),))
print(fst.union(snd))
