Find the difference between two sets, namely ${\frac{7}{\sqrt{2}}, -1, \frac{25}{\pi }, -\frac{24}{\pi }, \frac{8}{3}, -2} \setminus {-\frac{7}{2}, \frac{7}{\sqrt{2}}, -7, \frac{25}{\pi }}$.

import math

fst = set(((7/(math.sqrt(2))), -1, (25/math.pi), -(24/math.pi), (8/3), -2,))
snd = set((-(7/2), (7/(math.sqrt(2))), -7, (25/math.pi),))
print(fst - snd)
