If you were for any reason needing to worry that interpreters might not be
installed into the path you're expecting, you'd usually use env. While it
would be very very silly to move sh out of /bin, if you're writing python
or perl the site administrator can put those in interesting places if they
wish. So you could use something like

#!/usr/bin/env python

and env should pass the execution of the script to the interpreter you've
specified.
