Find the difference between two sets, namely ${\frac{23}{5}, 4, 10, 5, 2.26, 1, -6, 4.1} \setminus {-6, 5 \sqrt{2}, \frac{7}{\sqrt{2}}, 1, -\frac{15}{2}, 5, 2.26}$.

import math

fst = set(((23/5), 4, 10, 5, 2.26, 1, -6, 4.1,))
snd = set((-6, 5*math.sqrt(2), (7/(math.sqrt(2))), 1, -(15/2), 5, 2.26,))
print(fst - snd)
