Find the difference between two sets, namely ${8, -7.9, -1, -\frac{19}{2}, 3, 3 \sqrt{5}, -\frac{6}{\sqrt{\pi }}} \setminus {8, -\frac{11}{\sqrt{\pi }}, 3 \sqrt{5}}$.

import math

fst = set((8, -7.9, -1, -(19/2), 3, 3*math.sqrt(5), -(6/(math.sqrt(math.pi))),))
snd = set((8, -(11/(math.sqrt(math.pi))), 3*math.sqrt(5),))
print(fst - snd)
