Pairwise Set Intersection in Python

Question

If I have a variable number of sets (let\'s call the number n), which have at most m elements each, what\'s the most efficient way to calculate the pairwise in

Answer 1

How about using intersection method of set. See below:

A={"a","b","c"}
B={"c","d","e"}
C={"a","c","e"}

intersect_AB = A.intersection(B)
intersect_BC = B.intersection(C)
intersect_AC = A.intersection(C)

print intersect_AB, intersect_BC, intersect_AC
