True, except that it doesn't meet the OP's requirements. The OP wanted to be able to specify a range of versions. The problem with changing the shebang line is that there's no way to say "python 2.5 or 2.6 or 2.7" Regardless, it's much better to do #!/usr/bin/evn python2.6 instead of hard-coding the path because not everyone has their interpreter in the same spot. I have the Macports python 2.6.4 installed in /opt/local/bin and I'd get kind of annoyed if a script, insisted on using the 2.6.1 that came with the system, especially if it depends on 3rd party libraries. > 2009/11/11 Benjamin Kaplan <benjamin.kap...@case.edu>: >> On Wed, Nov 11, 2009 at 12:16 PM, kj <no.em...@please.post> wrote: >>> >>> >>> >>> >>> I have a script that must be run with Python 2.6.x.
