Enumerating Subset Sums

I learned how to enumerate the subset sums of a set.
*For example, for a set a = {8, 3, 7, 2, 5}, this would result in something like {0, 2, 3, 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 20, 22, 23, 25}.

    a = map(int, input().split())
    sub = set()
    sub.add(0)
    for i in a:
        for j in list(sub):
            sub.add(i+j)

I also learned that it can be written more concisely as follows:

    a = map(int, input().split())
    sub = {0}
    for i in a:
        sub |= {i + j for j in sub}

Additionally, to sort the subset sums added to the set:

sorted(list(sub))

I also learned that list(sub) can be written as [*sub].
