Find the difference between two sets, namely ${-7, -4, -1, 1, 2 \sqrt{2}, -3 \sqrt{5}, \frac{29}{\pi }} \setminus {2 \sqrt{2}, -4, -3 \sqrt{5}, -\frac{23}{7}, 3, 7}$.

import math

fst = set((-7, -4, -1, 1, 2*math.sqrt(2), -3*math.sqrt(5), (29/math.pi),))
snd = set((2*math.sqrt(2), -4, -3*math.sqrt(5), -(23/7), 3, 7,))
print(fst - snd)
