Answer 1

it's like this:

0 * "*" + (10-0) * "*" meaning 0 stars at beginning + 10 stars at end
1 * "*" + (10-1) * "*" meaning 1 star at beginning + 9 stars at end
2 * "*" + (10-2) * "*" meaning 2 stars at beginning + 8 stars at end
3 * "*" + (10-3) * "*" meaning 3 stars at beginning + 7 stars at end
4 * "*" + (10-4) * "*" meaning 4 stars at beginning + 6 stars at end
5 * "*" + (10-5) * "*" meaning 5 stars at beginning + 5 stars at end
6 * "*" + (10-6) * "*" meaning 6 stars at beginning + 4 stars at end
7 * "*" + (10-7) * "*" meaning 7 stars at beginning + 3 stars at end
8 * "*" + (10-8) * "*" meaning 8 stars at beginning + 2 stars at end
9 * "*" + (10-9) * "*" meaning 9 stars at beginning + 1 star at end
10 * "*" + (10-10) * "*" meaning 10 stars at beginning + 0 stars at end

Answer 2

for i in range(10):
print(10 * "*")
Is more simpler anyways, n * aString returns the string repeated n times like 2 * "foo" is "foofoo".
