Find the difference between two sets, namely ${\frac{19}{5}, -4 \sqrt{2}, \sqrt{2}, 1, -\frac{9}{\sqrt{2}}} \setminus {-2 \sqrt{2}, \frac{19}{5}, -6 \log (2), -\frac{11}{\sqrt{2}}, -\frac{9}{\sqrt{2}}, 1, \frac{39}{5}, -9}$.

import math

fst = set(((19/5), -4*math.sqrt(2), math.sqrt(2), 1, -(9/(math.sqrt(2))),))
snd = set((-2*math.sqrt(2), (19/5), -6*math.log(2), -(11/(math.sqrt(2))), -(9/(math.sqrt(2))), 1, (39/5), -9,))
print(fst - snd)
