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:

>>> import codecs >>> codecs.decode('ab', 'hex') b'\xab'

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

>>> import base64 >>> base64.b16decode('AB') b'\xab'

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

>>> import binascii >>> binascii.unhexlify('ab') b'\xab'

Either way, you'll get a?bytes?object.

?

使用第二種方式解決了:

>>> import base64 >>> base64.b16decode('AB')

?
