Today I learned that Python has built-in functions to assess whether two sets are disjoints (i.e. have no elements in common).

set1 = {1, 2, 3, 4}
set2 = {3, 4, 5, 6}

print(set1.isdisjoint(set2))

False

Alternatively, you can use the intersection() function to find the points of intersection between two sets:

intersects = set1.intersection(set2)
print(intersects)

{3, 4}
