numpy.ma.filled() function – Python
numpy.ma.filled() function return input as an array with masked data replaced by a fill value. If arr is not a MaskedArray, arr itself is returned. If arr is a MaskedArray and fill_value is None, fill_value is set to arr.fill_value.
Syntax : numpy.ma.filled(arr, fill_value = None)
Parameters :
arr : [MaskedArray or array_like] An input object.
fill_value : [scalar, optional] Filling value. Default is None.Return : [ndarray] The filled array.
