Alan Meyer <amey...@yahoo.com>:I presume it would still be a good idea to test both python interpreters against any script that you didn't knowingly write with a feature that will only work in one of the two python versions. If it works fine in both - and many will, then use: #!/usr/bin/env python Only use the "python2" or "python3" versions if you really have a reason to do so. Yes? No?No. Even if you managed to do that, it would mean getting the worst of both worlds. The language dialects are too far apart. When you start your Python project, you decide between Python 2 and Python 3 and go all in.
Plenty of people have adopted a dual-support strategy, with one code base that supports both Python 2 and Python 3. The six module can help a great deal with this.
