Find the union of the following sets, namely ${-\sqrt{5}, -5 \sqrt{3}, -5.3, -5, 5, \frac{17}{\pi }} \cup {-5., -5, \frac{17}{\pi }, -3 \sqrt{5}, -5 \sqrt{3}}$.

import math

fst = set((-math.sqrt(5), -5*math.sqrt(3), -5.3, -5, 5, (17/math.pi),))
snd = set((-5., -5, (17/math.pi), -3*math.sqrt(5), -5*math.sqrt(3),))
print(fst.union(snd))
