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 ofdata memory. The bytes object is produced in C-order by default.This behavior is controlled by theorder 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 forAny) means ‘F’ ifa isFortran contiguous, ‘C’ otherwise. Default is ‘C’.

Returns:

sbytes

Python bytes exhibiting a copy ofa’s raw data.
