python 解码编码十六进制

Initial byte string s = b'hello' Encode as hex import binascii h = binascii.b2a_hex(s) h b'68656c6c6f' Decode back to bytes binascii.a2b_hex(h) b'hello'

or

import base64 h = base64.b16encode(s) h b'68656C6C6F' base64.b16decode(h) b'hello'

base64

Some byte data s = b'hello' import base64

Encode as Base64 a = base64.b64encode(s) a b'aGVsbG8='

Decode from Base64 base64.b64decode(a) b'hello'
