Find the difference between two sets, namely ${-\frac{13}{e}, \frac{6}{e}, -8, \frac{23}{4}, -\sqrt{2}, 5.19, 1} \setminus {4, 5.19, \frac{23}{4}, -6, \frac{6}{e}, 10}$.

import math

fst = set((-(13/math.e), (6/math.e), -8, (23/4), -math.sqrt(2), 5.19, 1,))
snd = set((4, 5.19, (23/4), -6, (6/math.e), 10,))
print(fst - snd)
