Find the difference between two sets, namely ${0, -5.42, 0.6, -7 \sqrt{2}, 7, 4, -\frac{18}{\sqrt{5}}} \setminus {-5.42, -1, -\frac{18}{\sqrt{5}}, 0.6, 7, 0}$.

import math

fst = set((0, -5.42, 0.6, -7*math.sqrt(2), 7, 4, -(18/(math.sqrt(5))),))
snd = set((-5.42, -1, -(18/(math.sqrt(5))), 0.6, 7, 0,))
print(fst - snd)
