Hex and serial variable

[deal0703]

Hi all,

I am new to pyhton and pyserial and got a question please.

I got a file with hex code

final_CW
b'\xEA\x10\xC6\x26\x4B\x37\xE4\x87\xC3\x2E\xB2\xB6\x9F\x07\x3D\x2D\xC6\x30'

I'd like to send this array to the serial port.

f=open("final_CW","r")
CW = f.read()
print("Send CW")
f.close()
ser.write(CW)

I'd like to send

CW = b'\xEA\x10\xC6\x26\x4B\x37\xE4\x87\xC3\x2E\xB2\xB6\x9F\x07\x3D\x2D\xC6\x30'
ser.write(CW)

I am getting the following error if I read from file.

File "x.last", line 8049, in <module>
ser.write(CW)
File "/usr/lib/python3/dist-packages/serial/serialposix.py", line 518, in write
d = to_bytes(data)
File "/usr/lib/python3/dist-packages/serial/serialutil.py", line 63, in to_bytes
raise TypeError('unicode strings are not supported, please encode to bytes: {!r}'.format(seq))
TypeError: unicode strings are not supported, please encode to bytes: "b' \\xEA\\x10\\xC6\\x26\\x4B\\x37\\xE4\\x87\\xC3\\x2E\\xB2\\xB6\\x9F\\x07\\x 3D\\x2D\\xC6\\x30'\n"

Thanks for any help.
