If you write a shebang manually then always use #!/usr/bin/env python unless you have a specific reason not to use it. This form is understood even on Windows (Python launcher). Note: installed scripts should use a specific python executable e.g., /usr/bin/python or /home/me/. virtualenvs/project/bin/python .
