Practic = set() - Python
set1 = {1,3,5,7,9, -2}
set2 = {2,4,6,8,0, -2}
# union
print(set1.
union(set2))
# or
print(set1 | set2)
# result {0, 1, 2, 3, 4, 5, 6, 7, 8, 9, -2}
# difference
print(set1.
difference(set2))
# or
print(set1 - set2)
# result {1, 3, 5, 7, 9}
# intersection
print(set1.
intersection(set2))
# or
print(set1 & set2)
# result {-2}
# symmetric_difference
print(set1.
symmetric_difference(set2))
# or
print(set1 ^ set2)
# result {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
