An alternative that also has the added benefit of easily logging its output:
hexs = "13 00 00 00 08 00"
logging.debug(hexs)
key = bytearray.fromhex(hexs)
allows you to do easy substitutions like so:
hexs = "13 00 00 00 08 {:02X}".format(someByte)
logging.debug(hexs)
key = bytearray.fromhex(hexs)
Dietrich's answer is probably just the thing you need for what you describe, sending bytes, but a closer analogue to the code you've provided for example would be using the bytearray
type.
>>> key = bytearray([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])
>>> bytes(key)
b'\x13\x00\x00\x00\x08\x00'
>>>
Just use a bytearray
(Python 2.6 and later) which represents a mutable sequence of bytes
>>> key = bytearray([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])
>>> key
bytearray(b'\x13\x00\x00\x00\x08\x00')
Indexing get and sets the individual bytes
>>> key[0]
19
>>> key[1]=0xff
>>> key
bytearray(b'\x13\xff\x00\x00\x08\x00')
and if you need it as a str
(or bytes
in Python 3), it's as simple as
>>> bytes(key)
'\x13\xff\x00\x00\x08\x00'
