numpy.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 ofdata memory. The bytes object can be produced in either ‘C’ or ‘Fortran’,or ‘Any’ order (the default is ‘C’-order). ‘Any’ order means C-orderunless the F_CONTIGUOUS flag in the array is set, in which case itmeans ‘Fortran’ order.

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

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 ofa‘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'
