Understanding the Append Function in NumPy

array: The input array.

values: The values to be appended. These can be single elements or arrays.

axis: The axis along which the values are appended. If not specified, the array is flattened before the operation.

Here, the array [5, 6] is appended to the original array.

Appending Along a Specific Axis

If you are working with multidimensional arrays, you can specify the axis along which the append operation should occur. Consider the following example:
