Find the difference between two sets, namely ${-\frac{29}{5}, -e, -\frac{4}{\sqrt{\pi }}, -3 \sqrt{2}, 3 \pi} \setminus {-e, -\sqrt{2}, -\frac{4}{\sqrt{\pi }}, 7., 3 \pi, -\frac{43}{5}}$.

import math

fst = set((-(29/5), -math.e, -(4/(math.sqrt(math.pi))), -3*math.sqrt(2), 3*math.pi,))
snd = set((-math.e, -math.sqrt(2), -(4/(math.sqrt(math.pi))), 7., 3*math.pi, -(43/5),))
print(fst - snd)
