Find the union of the following sets, namely ${0, -2 \sqrt{2}, 0.65, -\frac{4}{e}, -\frac{25}{\pi }, -8.681, -9, -4, 3} \cup {-2 \sqrt{2}, -6.49, -\frac{4}{e}, -9, 0, 3, -1.667, 5, -\frac{25}{\pi }}$.

import math

fst = set((0, -2*math.sqrt(2), 0.65, -(4/math.e), -(25/math.pi), -8.681, -9, -4, 3,))
snd = set((-2*math.sqrt(2), -6.49, -(4/math.e), -9, 0, 3, -1.667, 5, -(25/math.pi),))
print(fst.union(snd))
