numpy.ndarray.tobytes#

method

ndarray.tobytes(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 is produced in C-order by default. This behavior is controlled by the order parameter.

Parameters:

order{C, F, A}, optional

Controls the memory layout of the bytes object. C means C-order, F means F-order, A (short for Any) means F if a is Fortran contiguous, C otherwise. Default is C.

Returns:

sbytes

Python bytes exhibiting a copy of as raw data.

>>> x.tobytes()
b'\x00\x00\x01\x00\x02\x00\x03\x00'
>>> x.tobytes('C') == x.tobytes()
True
>>> x.tobytes('F')
b'\x00\x00\x02\x00\x01\x00\x03\x00'
