I could not quite understand what you are trying to achieve, but
it appears that you want to convert a character strings of hexadecimal
characters into a byte string with the same bytes. I recommend this:

py> import binascii
py> binascii.a2b_hex("001485e55503")
'\x00\x14\x85\xe5U\x03'

Of course, if the string is fixed, you could just as well use the
result string (i.e. '\x00\x14\x85\xe5U\x03') directly.
