All tutorials will tell you to start it with
#!/usr/bin/env python
which will start python2 on all (?) existing linux distros, but is
expected to start python3 within the next decade.

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?
