Find the union of the following sets, namely ${-\frac{23}{3}, -3.8, \frac{31}{\pi }, -4.6, 0, -7, -6, 9} \cup {\frac{18}{e}, -9.7, \frac{31}{\pi }, -1, -\frac{23}{3}, -6, -\sqrt{2}, -3.8}$.

import math

fst = set((-(23/3), -3.8, (31/math.pi), -4.6, 0, -7, -6, 9,))
snd = set(((18/math.e), -9.7, (31/math.pi), -1, -(23/3), -6, -math.sqrt(2), -3.8,))
print(fst.union(snd))
