How can the python interpreter read the charaset?

I'm learning python. And i learned every comment starts with a hash "#". So how can the python interpreter read this line?

# -*- coding: utf-8 -*-

and set the charset to utf-8 ? (I'm using Python 2.7.3) Thank you in advance.

Yes, it is a comment. But this does not mean that python doesn't see it. So it can obviously parse it, too.

What python actually does is using the regular expression coding[:=]\s*([-\w.]+) on the first two lines. Most likely this is done even before the actual python parser steps in.

See PEP-0263 for details.
