I was trying to get a series of sum from 1 to n, 2 to n, ..., and n

For example, if n=5, then the result should be 15 14 12 9 5

Please comment for the code below. I can't figure out what's wrong.

n=int(input())
sum=0
m=0
factorial=1for i in range(1, n + 1):factorial *= isum=factorial-mprint(sum)

One reasonably simple approach:

n = 5
s = sum(range(n+1))
for i in range(n):s -= iprint(s)15
14
12
9
5
