Find the union of the following sets, namely ${-0.236, -10, 5, 0.8, -4, 9, -1} \cup {8.2, 5, 9, \frac{21}{\pi }, -1, 4.3, -4.244, -10, -4, -9, 3 e}$.

import math

fst = set((-0.236, -10, 5, 0.8, -4, 9, -1,))
snd = set((8.2, 5, 9, (21/math.pi), -1, 4.3, -4.244, -10, -4, -9, 3*math.e,))
print(fst.union(snd))
