Python类方法:减去两个向量

class Vector:
    def __init__(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z
    
    @classmethod
    def subtract(cls, vector1, vector2):
        result_x = vector1.x - vector2.x
        result_y = vector1.y - vector2.y
        result_z = vector1.z - vector2.z
        return cls(result_x, result_y, result_z)

# 创建两个向量对象
vector1 = Vector(1, 2, 3)
vector2 = Vector(4, 5, 6)

# 调用类方法减去两个向量
result_vector = Vector.subtract(vector1, vector2)

# 输出结果向量的坐标
print(result_vector.x, result_vector.y, result_vector.z)
