python encode()


No, using encode() to hexlify isn't nice.

The way you use the hex codec worked in Python 2 because you can call encode() on 8-bit strings in Python 2, ie you can encode something that is already encoded. That doesn't make sense. encode() is for encoding Unicode strings into 8-bit strings, not for encoding 8-bit strings as 8-bit strings.

In Python 3 you can't call encode() on 8-bit strings anymore, so the hex codec became pointless and was removed.

Although you theoretically could have a hex codec and use it like this:

>>> import codecs>>> hexlify = codecs.getencoder('hex')>>> hexlify(b'Blaah')[0]b'426c616168'

Using binascii is easier and nicer:

>>> import binascii>>> binascii.hexlify(b'Blaah')b'426c616168'


this is the same answer for the above but i modified it so it works with python 3.
