Juli 2011 16:00 An: django-users@googlegroups.com Betreff: Re: change values in "select list" Don't take it personally, but while we're at it, I should tell you that Classes have CamelCase names and functions are lowercase_with_underscores. Try not to mix both unless you have an incredibly compelling reason (which is not the case here). For what it's worth, it will do you good to name everything in English, even if it's not your native language. Python's keywords are in English (if, while, for, class, return, break...) and sticking to one language makes the code easier to maintain (you might have a developer on your team who doesn't speak German) and readable for those of us who can only speak a language or two.
