I have a Python 2.6 program (a code generator, actually) that tries
several methods of compressing a string and chooses the most compact.
It then writes out something like this:
{ encoding='bz2_codec', data = '...'}
I'm having two problems converting this to Py3. First is the absence
of the bz2_codec, among others. It was very convenient for my program
to delay selection of the decoding method until run-time and then have
an easy way to load the appropriate code. Is this gone forever from
the standard libraries?
Second, I would write my data out using the 'string_escape' codec.
It, too, has been removed; there's a 'unicode_escape' codec which is
similar, but I would rather use a 'byte_escape' codec to produce
literals of the form b'asdf'. Unfortunately, there isn't one that I
can find. I could use the repr function, but that seems less
efficient. Does anyone have any ideas? Thanks.
