Running a Flask app standalone is, if I'm not mistaken, good for
low-traffic usage only. Makes it absolutely ideal for debugging, but
not so great for production work. But since you don't have to change a
single line of application code to slot it into Apache, and presumably
likewise for working with haproxy or anything else, it's a worthwhile
simplicity.

I've taken a good number of students through a Python web programming
course, and we use Flask all the way. Testing? "python run.py".
Production? "git push heroku master". No effort required, no careful
juggling of "this bit makes it work in production".

Look into Flask. You can do something really simple:
https://github.com/Rosuav/MinstrelHall

All the code is in one file for simplicity, though for a larger
project, you can break it up as required. (Compared to PHP, where
you're _forced_ to have exactly one file per entry-point, this is a
nice flexibility.) Then I just have one line in my Apache config file
that looks something like this:

WSGIScriptAlias / /path/to/scripts/MinstrelHall/mh.wsgi

and Apache does all the rest. There's some cruft in that code to get
around a few oddities, but for the most part, writing a page is as
simple as writing a function, decorated to manage routing, that
returns render_template("somefile.html"). It's pretty easy.

will eventually have enough parts left over to build a second one.

Yes, that is a consideration. But hopefully the OP can explore some
possibilities and get to some more specific questions like "Apache is
complaining that WSGIScriptAlias is an unknown directive - how do I
correct this?", which are easily answered with a web search or a quick
post to some forum (preferably an Apache-related one, as this isn't a
Python question).

I think that bottle or flask won't seem complicated to you 

As I was walking around town it occurred to me to ask if you have
made your something.py file executable?  I don't even know if
apache on windows cares about such things, though if you are using cgi
and a unix like system you will need to do this.

Thank you very much.

I will definitely look into python web frameworks in the future, they seem
complicated to me compared to php for example. I am looking for the simplest
way to test my python scripts till I understand better how it works and when
I can configure my own web server to run the framework because I want develop my

I'm not a Windows user.  You are going to have to get help with this
from somebody else.

While in the long run you're better off if you follow Chris' advice here's a 
minimal cgi script run with http.server
(I'm using curl instead of a browser).

$ mkdir cgi-bin
$ echo -e '#!/usr/bin/env 
python3\nprint("Content-type:text/plain")\nprint()\nprint("Hello, world")' > 
cgi-bin/index.py
$ chmod u+x cgi-bin/index.py

This is really great advice, and if your idea is 'but I don't want
anything as _big_ as a framework, look at flask http://flask.pocoo.org/
and bottle http://bottlepy.org/docs/dev/index.html  both of which
are tiny microframeworks.

Don’t use http.server. Don’t use CGI. This is not how things work in Python.

In Python, you should use a web framework to write your code. Web
frameworks include Flask, Django, Pyramid… Find one that’s popular and
that you like, and learn that. You won’t have any `.py` URLs, instead
you will have modern pretty URLs with no extensions. And a lot of
things will be abstracted — no manual header creation, help with safe
forms and databases.

And then you will need to figure out how to run it. I personally use
nginx and uwsgi for this, you may need to look for something else.

Examples for Django:

What operating system are you running?  It sounds to me as if you haven't
configured apache to add a Handler for python scripts, or you have, but
forgot to restart apache after you did so.
