请问为什么文中程序运行会提示越界呢

Question

输入数据：
5 3
4 4 1 2 1

n, m = map(int, input().split())
w = [int(0)*(n+1)]
s = [int(0)*(m+1)]
w = list(map(int, input().split()))
for i in range(1,n+1):
    maxx = 1
    for j in range(2, m+1):
        if s[maxx] > s[j]:
            maxx = j
        s[maxx] += w[i-1]
maxx = 1
j = 0
for j in range(1,m+1):
    if s[j] > maxx:

    maxx = s[i]
else:
    continue

print(maxx)

Answer 1

s = [int(0)*(m+1)] 这么赋值，s不就是中有一个0的列表[0]吗？肯定越界
