Find the difference between two sets, namely ${-\frac{17}{7}, 8, -8.169, 0.28, 6, -2} \setminus {6, -2, -4, \frac{1}{\sqrt{5}}, 8, 2 \sqrt{3}, \frac{25}{7}}$.

import math

fst = set((-(17/7), 8, -8.169, 0.28, 6, -2,))
snd = set((6, -2, -4, (1/(math.sqrt(5))), 8, 2*math.sqrt(3), (25/7),))
print(fst - snd)
