hexadecimal string to byte array in python

python bytearray

Suppose your hex string is something like

>>> hex_string = "deadbeef"

>>> hex_data = hex_string.decode("hex")>>> hex_data"\xde\xad\xbe\xef"

>>> bytes.fromhex(hex_string)  # Python ≥ 3b'\xde\xad\xbe\xef'>>> bytearray.fromhex(hex_string)bytearray(b'\xde\xad\xbe\xef')

Note that bytes is an immutable version of bytearray.

python bytearray

There is a built-in function in bytearray that does what you intend.

bytearray.fromhex("de ad be ef 00")

It returns a bytearray and it reads hex strings with or without space separator.

python bytearray

provided I understood correctly, you should look for binascii.unhexlify

import binasciia='45222e's=binascii.unhexlify(a)b=[ord(x) for x in s]
