For the record quoting from http://www.python.org/dev/peps/pep-0397/

"As Python 3.x scripts are often syntactically incompatible with Python 
2.x scripts, a different strategy must be used to allow files with a 
'.py' extension to use a different executable based on the Python 
version the script targets. This will be done by borrowing the existing 
practices of another operating system - scripts will be able to nominate 
the version of Python they need by way of a "shebang" line, as described 
below."
