Very good point. Additionally, with insert and delete we might need to apply the rules of broadcasting [0]. For example, if I have a 2-dimensional array and I insert a scalar value by using axis=0, the scalar value needs to be broadcasted to match the column dimension of the array: >>> a = np.array([[1,2],[3,4],[5,6]]) >>> np.insert(a, 1, 11, axis=0) array([[ 1, 2], [11, 11], [ 3, 4], [ 5, 6]]) [0] https://jakevdp.github.io/PythonDataScienceHandbook/02.05-computation-on-arrays-broadcasting.html#Rules-of-Broadcasting https://jakevdp.github.io/PythonDataScienceHandbook/02.05-co...
