Find the union of the following sets, namely ${6.2, -3 \sqrt{2}, \frac{6}{\pi }, 7, \frac{15}{7}} \cup {-\frac{54}{7}, -4, \frac{6}{\pi }, 7, -\frac{4}{\sqrt{3}}}$.

import math

fst = set((6.2, -3*math.sqrt(2), (6/math.pi), 7, (15/7),))
snd = set((-(54/7), -4, (6/math.pi), 7, -(4/(math.sqrt(3))),))
print(fst.union(snd))
