STINNER Victor <[email protected]> added the comment:
base64, bz2, hex, quopri, rot13, uu and zlib codecs (reintroduced recently by
r86934, issue #7475) cannot be used by str.encode/bytes.decode, but with
.transform() and .untransform() methods of bytes and str objects. But these
methods were removed by r87176.
The last solution to use base64 codec is:
>>> import codecs
>>> codecs.lookup('base64').decode(b'YWJj\n')[0]
b'abc'
>>> codecs.lookup('base64').encode(b'YWJj\n')[0]
b'abc'
Or simply use directly the base64 module:
>>> import base64
>>> base64.decodebytes(b'YWJj\n')
b'abc'
>>> base64.encodebytes(b'abc')
b'YWJj\n'
base64, bz2, hex, quopri, rot13, uu and zlib codecs should be removed from
encodings.aliases (because they introduced a confusion for Python 2 users), or
removed completly (because it's easier to use directly the related module, eg.
base64 or zlib).
