Let's have a look at an example of a 2-D array with axis numbering:

Let's have a look at an example of indexing (both positive and negative) in 2-D arrays:

Let's examine the syntax of slicing: array[start_row: end_row: step_row, start_column: end_column: step_column], where:

• start_row is the index from which row slicing begins;

• end_row is the index where row slicing stops (note that this index is not included);

• step_row is the parameter that specifies the intervals between row indices;

• start_column is the index from which column slicing starts;

• end_column is the index where column slicing ends (note that this index is not included);

• step_column is the parameter that determines the intervals between column indices.

Now, let's refer to the following image:
