** numpy.ma.append()** function append the values to the end of an array.

Syntax :numpy.ma.append(arr1, arr2, axis = None)Parameters :arr1 :[array_like] Values are appended to a copy of this array.arr2 :[array_like] Values are appended to a copy of this array. If axis is not specified, arr2 can be any shape and will be flattened before use. Otherwise, it must be of the correct shape.axis :[int, optional] The axis along which value are appended.Return :[MaskedArray] A copy of arr1 with arr2 appended to axis. If axis is None, the result is a flattened array.
