You cannot decode string objects; they are already decoded. You'll have to use a different method.

You can use the codecs.decode() function to apply hex as a codec:

>>>>

This applies a @L_403_1@ codec; it is the equivalent of using the base64.b16decode() function,with the input string converted to uppercase:

>>>>

You can also use the binascii.unhexlify() function to 'decode' a sequence of hex digits to bytes:

>>>>

Either way,you'll get a bytes object.

使用第二种方式解决了:
