A = {1, 2, 3, 4}
B = {1, 2 ,4,5,6,7,9}
C = {1, 2,11,3}
print("The union between set A and set B is",A.union(B))
print("The union between set A and set C is",A.union(C))
print("The union between set C and set B is",B.union(C))
Output:
The union between set A and set B is {1, 2, 3, 4, 5, 6, 7, 9}
The union between set A and set C is {1, 2, 3, 4, 11}
The union between set C and set B is {1, 2, 3, 4, 5, 6, 7, 9, 11}
