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? Forgive me this question, I am a Windows-user. Is it just a user habit, where do you put your Python? Is any of these more canonical?

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