Find the difference between two sets, namely ${-4, 0, 3, \frac{17}{e}, \frac{15}{4}, 8, -\sqrt{2}} \setminus {0, 3, -\frac{26}{5}, 8, 3 \sqrt{2}, -4, -\frac{8}{e}}$.

import math

fst = set((-4, 0, 3, (17/math.e), (15/4), 8, -math.sqrt(2),))
snd = set((0, 3, -(26/5), 8, 3*math.sqrt(2), -4, -(8/math.e),))
print(fst - snd)
