Nothing. If you look at the documentation, np.append does not modify
in place the array.:
'''
Returns
-------
out : ndarray
A copy of `arr` with `values` appended to `axis`. Note that `append`
does not occur in-place: a new array is allocated and filled.
'''
Modification in place is not possible with the numpy model of an array.
