Python set operations (union, intersection, difference and symmetric difference)
This article demonstrates different operations on Python sets.
Examples:
Input :
A = {0, 2, 4, 6, 8}
B = {1, 2, 3, 4, 5}
Output :
Union : [0, 1, 2, 3, 4, 5, 6, 8]
Intersection : [2, 4]
Difference : [8, 0, 6]
Symmetric difference : [0, 1, 3, 5, 6, 8]
In Python, below quick operands can be used for different operations.
| for union.
& for intersection.
– for difference
^ for symmetric difference
# Program to perform different set operations# as we do in mathematics # sets are defineA = {0, 2, 4, 6, 8};B = {1, 2, 3, 4, 5}; # unionprint("Union :", A | B) # intersectionprint("Intersection :", A & B) # differenceprint("Difference :", A - B) # symmetric differenceprint("Symmetric difference :", A ^ B) |
Output:
('Union :', set([0, 1, 2, 3, 4, 5, 6, 8]))
('Intersection :', set([2, 4]))
('Difference :', set([8, 0, 6]))
('Symmetric difference :', set([0, 1, 3, 5, 6, 8]))
