numpy.ma.MaskedArray.tobytes#

method

ma.MaskedArray.tobytes(fill_value=None, order='C')[source]#

Return the array data as a string containing the raw bytes in the array.

The array is filled with a fill value before the string conversion.

Parameters:

fill_valuescalar, optional

Value used to fill in the masked values. Default is None, in which case MaskedArray.fill_value is used.

order{C,F,A}, optional

Order of the data item in the copy. Default is C.

• C C order (row major).

• F Fortran order (column major).

• A Any, current order of array.

• None Same as A.

As for ndarray.tobytes, information about the shape, dtype, etc., but also about fill_value, will be lost.
