Indexing [::-1] to Reverse ALL 2D Array Rows, ALL 3D, 4D Array Columns & Rows Python

[Jeremy7]

You should try: https://numpy.org/doc/stable/reference/g...numpy-flip

Thanks for your help; I'm aware of numpy.flip(). numpy.flip() works great, but I wanted to only use the index. I got the following answers with some help from Stack Overflow and another source:
[:,::-1] reverses 2D array rows, [:,::-1,:] reverses 3D array columns, [:,:,::-1] reverses 3D array rows, [:,:,::-1,:] reverses 4D array columns, [:,:,:,::-1] reverses 4D array rows
