Find the union of the following sets, namely ${-5.89, 6, -2, -\frac{30}{7}, -3, 5, -4} \cup {-4, 9, -2, 5.21, -\frac{4}{3}, 6, -\frac{30}{7}, \sqrt{2}}$.

import math

fst = set((-5.89, 6, -2, -(30/7), -3, 5, -4,))
snd = set((-4, 9, -2, 5.21, -(4/3), 6, -(30/7), math.sqrt(2),))
print(fst.union(snd))
