用python设计一个三维向量类 并实现向量的加法、减法以及向量与标量的乘法和除法运算(要求重载__add__、__sub__、__mul__等方法)。

好的,我知道了。下面是你要求的三维向量类的Python代码:
```python
class Vector3D:
def __init__(self, x, y, z):
self.x = x
self.y = y
self.z = z
def __add__(self, other):
return Vector3D(self.x + other.x, self.y + other.y, self.z + other.z)
def __sub__(self, other):
return Vector3D(self.x - other.x, self.y - other.y, self.z - other.z)
def __mul__(self, other):
if isinstance(other, Vector3D):
return self.x * other.x + self.y * other.y + self.z * other.z
elif isinstance(other, int) or isinstance(other, float):
return Vector3D(self.x * other, self.y * other, self.z * other)
def __truediv__(self, other):
if isinstance(other, int) or isinstance(other, float):
return Vector3D(self.x / other, self.y / other, self.z / other)
def __repr__(self):
return f"({self.x}, {self.y}, {self.z})"
```
这个类可以完成向量的加法、减法、标量乘法和标量除法运算。你可以在代码中看到方法的实现细节。如果你有任何问题,请随时向我询问。
