python - 如何接收带有负号的数字列表？

Question

我试过这个，但它给了我这个错误：SyntaxError: illegal expression for augmented assignment。

输入将是这样的：-2 4 -1

x_forces, y_forces, z_forces = 0
x_forces, y_forces, z_forces += map(int, input().split(' '))

这是你要找的吗？

x_forces, y_forces, z_forces = 0, 0, 0
n = [i for i in map(int, input().split(' '))]

x_forces += n[0]
y_forces += n[1]
z_forces += n[2]

print(x_forces, y_forces, z_forces)
