Send raw string via socket with out any changes

[john36]

Hi,
I have problem with sending raw string data via socket. I made communication between PC(python script) and labeler Markem Imaje. Labeler has RS232 and converter Ethernet/RS232 and i have to send raw string data to converter with out any changes for example:

\x01\x81\xaa\x76\x00\x5d\x44\x00\x00\x00\x00\x57\x47\x5f\...

if I do something like this is working and labeler take mesage:

if labeler_connect_status:
    try:
        labeler_socket.send(b'\x01\x81\xaa\x76\x00\x5d\x44\x00\x00\x00\x00\x57\x47\x5f\...')
        print('DATA_SEND')
    except:
        print('ERROR_SEND')
        labeler_connect_status = False

but I have many different message and i want put raw string to variable:

if labeler_connect_status:
    variable = \x01\x81\xaa\x76\x00\x5d\x44\x00\x00\x00\x00\x57\x47\x5f\...
    try:
        labeler_socket.send(b'variable')#I know it doesn't work, but I want something like that
        print('DATA_SEND')
    except:
        print('ERROR_SEND')
        labeler_connect_status = False

I tried many options but it doesn't work because python try to encodes my data to UTF-8, ASCII...
for example when I want change string to bytes
\x01\x81\xaa\x76\x00\x5d\x44\x00\x00\x00\x00\x57\x47\x5f\... python send:
b'\x01\xc2\x81\xc2\xaav\x00]D\x00\x00\x00\x00WG_

My question is, how can I send raw data string as bytes with out any changes?
PLS help

P.S. I tried make variable string with b' - variable = b'\x01\x81\xaa\x76\x00\x5d\x44\x00\x00\x00\x00\x57\x47\x5f\' - but it didn't work
