To get the magnitude of a vector in NumPy, we can either define a function that computes the magnitude of a given vector based on a formula or we can use the norm() method in linalg module of NumPy. Here, linalg

Vector2d的组件可以直接作为属性访问(无需 getter 方法调用)。 ② Vector2d可以解包为一组变量的元组。 ③ Vector2d的repr模拟了构造实例的源代码。 ④ 在这里使用eval显示Vector2d的repr是其构造函数调用的忠实表示。² ⑤ Vector2d支持与==的比较;这对于测试很有用。
