Find the union of the following sets, namely ${\frac{13}{\sqrt{2}}, 1, 7.51, \frac{33}{4}, -4, \frac{18}{e}} \cup {-\frac{37}{4}, \frac{18}{e}, -6.94, -4, 4, -7, 7, \frac{13}{\sqrt{2}}}$.

import math

fst = set(((13/(math.sqrt(2))), 1, 7.51, (33/4), -4, (18/math.e),))
snd = set((-(37/4), (18/math.e), -6.94, -4, 4, -7, 7, (13/(math.sqrt(2))),))
print(fst.union(snd))
