It can be simple and it can be difficult. I have found "http://python-future.org/compatible_idioms.html"; especially useful. > Did you run into any issues? Besides the already mentioned "urllib*" and "bytes/str" problems, I have had significant issues with "dict" (missing "iter*" methods, missing "has_key"). Another important problem domain are doctests with unicode results. > Did 2to3 do its job well I have not used "2to3" -- because I doubt, that it can handle important cases, i.e. when a Python 2 "str" must become a Python 3 bytes or when a "dict.{keys, values, items}" must be listified. -- https://mail.python.org/mailman/listinfo/python-list
