PythonHexEncodeBestPractice.txt

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'

Also the hex codec has been chucked in 3.x. I'm using binascii instead
