Find the difference between two sets, namely ${-\frac{47}{7}, 8, -3 \pi, -5, -4 \sqrt{5}, -2 \pi, 0, 3 \sqrt{5}} \setminus {3 \pi, 3 \sqrt{5}, 0, -3 \pi, -\frac{17}{\sqrt{5}}, 8, -5, -\frac{47}{7}}$.

import math

fst = set((-(47/7), 8, -3*math.pi, -5, -4*math.sqrt(5), -2*math.pi, 0, 3*math.sqrt(5),))
snd = set((3*math.pi, 3*math.sqrt(5), 0, -3*math.pi, -(17/(math.sqrt(5))), 8, -5, -(47/7),))
print(fst - snd)
