The first line of pywki moduls is: #!/usr/bin/python Elsewhere I see #! /usr/bin/env/python, and (as far as I remember) this is stated at docs.python.org, too. What is the difference?

The second line is usually: # -*- coding: utf-8 -*- Elsewhere I see #coding: utf-8 Is there any difference? -- Bináris
