I would like to know if there is a way to create web pages without a huge framework in python.

I think of something like PHP/Apache, which comes just as a language and not with to much overhead (but I don't like PHP...). In PHP there is no ORM, no template engine, etc. But it is very very easy to just print a Hello World to the browser.

I know about Django and really like it, but it is a bit too big for simple web portals (5-10 pages).

I really like something simple, without installing too much.

Have you looked up Flask?

It's a much more minimalistic framework, and very easy to set up and get started.
