matrix.tostring()

matrix.tostring(order='C')

Construct Python bytes containing the raw data bytes in the array.

Constructs Python bytes showing a copy of the raw contents of data memory. The bytes object can be produced in either ?C? or ?Fortran?, or ?Any? order (the default is ?C?-order). ?Any? order means C-order unless the F_CONTIGUOUS flag in the array is set, in which case it means ?Fortran? order.

This function is a compatibility alias for tobytes. Despite its name it returns bytes not strings.

Parameters:

Parameters:	order : {?C?, ?F?, None}, optional Order of the data for multidimensional arrays: C, Fortran, or the same as for the original array.
Returns:	s : bytes Python bytes exhibiting a copy of `a`?s raw data.

order : {?C?, ?F?, None}, optional

Order of the data for multidimensional arrays: C, Fortran, or the same as for the original array.

Returns:

s : bytes

Python bytes exhibiting a copy of a?s raw data.

Examples

>>> x = np.array([[0, 1], [2, 3]])
>>> x.tobytes()
b'\x00\x00\x00\x00\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00'
>>> x.tobytes('C') == x.tobytes()
True
>>> x.tobytes('F')
b'\x00\x00\x00\x00\x02\x00\x00\x00\x01\x00\x00\x00\x03\x00\x00\x00'
