如何在Python中对集合运行操作并收集结果？

set1 = {1, 2, 3, 4, 5}
set2 = {4, 5, 6, 7, 8}

union_set = set1.union(set2)

intersection_set = set1.intersection(set2)

difference_set = set1.difference(set2)

symmetric_difference_set = set1.symmetric_difference(set2)

is_subset = set1.issubset(set2)

is_superset = set1.issuperset(set2)

length = len(set1)

list1 = [1, 2, 3, 4, 5]
set_from_list = set(list1)

list_from_set = list(set1)
