Slicing and splitting python numpy arrays

sure! slicing and splitting are common operations when working with numpy arrays in python.
slicing allows you to extract a portion of an array by specifying a range of indices along each axis. this is done using the `:` symbol within square brackets. slicing in numpy is similar to slicing in python lists.
splitting an array involves dividing it into smaller arrays along a specified axis. numpy provides the `np.split()` function for this purpose. you can split an array into equal-sized subarrays or specify the indices at which to split the array.
here's a code example to demonstrate slicing and splitting with numpy arrays:
in this example:
we create a 3x3 numpy array.
we slice the array to extract a subarray containing elements from the first two rows and columns 1 and 2.
we split the array into two subarrays along the rows and print the results.
we split the array into three subarrays along the columns and print the results.
