As I understand different distros will be in different locations in your drive. Here are some suggestions that come to mind -

1. You could use UNIX alias to create shortcuts pointing to the different distros. Eg: alias py2="/usr/bin/python2.X". So when you run your script you could use py2 xx.py
2. Or other way could be to modify your PYTHON_PATH environment variable.
3. Or if I am not wrong there is a provision in sys module to get the current python version number. You could get that & deal appropriately.

This should do it...
