Wiki "AppStyleGuide": Not clear to new users

[c.buhtz@posteo.jp]

Hello,

related to https://wiki.debian.org/Python/AppStyleGuide

There are several problems with that page.

It is to short to be a single instance. Just add it as a section to the 
"LibraryStyleGuide" and rename it to "StyleGuide". This would help 
against to much fractioning of the documentation.

There are some codeblocks in that page. They lack of description and 
introduction. It is totally unclear in which language that code is. No 
shebang in the beginning. Is this bash? Which file should contain that 
code?

The date of that wiki page is from year 2014. So maybe its content is 
outdated and not relevant anymore?

Kind
