Instead, I'd advise to use sixer (available in Debian
Stretch/Buster/Sid) to produce a patch that you can submit upstream, or
embed in your package. Sixer will patch the code in a way so that it
works with both Python 2 and 3.

Note that it wont do *all* for you, like you'll have to convert print
statements into function calls manually, but it does a big chunk, which
is quite helpful.

I hope that helps,
Cheers,
