🔒 shape before versus past the handling by ravel method

[golden grove]

>>> print( predscore.shape )
(1, 1)
>>> print( predscore.ravel().shape )
(1,)

The purpose of snippet above: know the shape before and after ravel.

How to read the form of shape (1,) ? Semantically same as (1) notation?

predscore is a ndarray.

(1,) is a 1d array of 1 element, sure.

usually it's not written (1) because (1) in python is just 1 (an int, not a tuple of 1 element, whereas the shape is always a tuple)
