I am coding with Pythons `NumPy` module. If coordinates of a point in 3D space are described as `[1, 2, 1]`, wouldn't that be three dimensions, three axis, a rank of three? Or if that is one dimension then shouldn't it be points (plural), not point?

Here is the documentation:

> 
> In Numpy dimensions are called axes. The number of axes is rank.
>  For example, the coordinates of a point in 3D space [1, 2, 1] is an array of rank 1, because it has one axis. That axis has a length of
