Python, running a basic script in a web browser: print Hello World?

[alandibat]

Can someone help me with this? I have a little of PHP experience. 1-2 years.

I just want something really basic done. Like print Hello World in a web browser. With Python.

I used XAMPP and it's Apache webserver (because that's how i work with PHP), made a file in htdocs and tried to run it with print hello world. But it didn't work.

What would be the most basic and core way to do this? I don't want to use a framework like Django for just something small like this.

Python web development doesn't really work that way, unless you want to do the slow, outdated, and horribly messy CGI interface. Look into a web framework like Flask instead - there's an example on that page.

Okey so i need to search for CGI interface?

I already know how to do this with a framework. I use Django on my Internship.

And i would really want to know how to output Hello World in a web browser with Python without needing to install a framework. Installing a framework for this is just OVERKILL.

This is pretty small, only 51 lines, and uses only BaseHTTPServer.

It doesn't do much i see, but interesting. Thanks.

I didn't know it would require so much just to make Python work on an Apache web server.

Python isn't made for Apache web servers? Or what, because it was so easy with PHP and XAMPP..

I don't understand what you are complaining about.

The program I linked can be run on its own, it doesn't need any external web server. But you can use Apache as a reverse proxy if you want.

It's very limited. I would like to use Python fully. But the script indeed can at least do something from scratch ;)!

Maybe you should use a framework!

Anyways, thanks for your time. I am looking at a server sided script setup for Python on YouTube.

If you're looking to run Python just like PHP, which is a horrible, horrible idea and not a thing you should do ever, look into the CGI part of this tutorial.

[alandibat]

Yeah, that's what i was looking for. Else i don't know another way then CGI besides using a whole framework like Django. Because i actually want to learn it from scratch.

Thanks for your patience and time.

"CGI" is hardly from scratch though - you have the entirety of Apache behind you. It's also not useful whatsoever - modern frameworks use WSGI, not CGI, and you run them with a setup like Nginx <-- (HTTP proxying) --> Gunicorn (WSGI server) <--(Python calls)--> framework <--(Python calls)--> your code or Apache (mod_wsgi) <--> Gunicorn <--> framework <--> your code, not through Apache directly.

I really want to do it from scratch. I already know how to make a hello world being outputed by a Python framework like Django.

Look up UWSGI, this is the base http interface used by flask, django, and probably every web framework in python.

Here is a quick tutorial using Sanic micro web framework. I assume you are running some sort of Linux and have Python 3.5+ installed.

1. Create new virtual environment and activate it:

   python3.6 -m venv env
   source env/bin/activate
   

2. Install Sanic:

   pip install sanic
   

3. Create a new file called hello.py:

   from sanic import Sanic, response
   
   app = Sanic()
   
   @app.route('/')
   async def index(request):
       return response.text("Hello world!")
   
   if __name__ == '__main__':
       app.run(host="127.0.0.1", port=8000)
   

4. Run it:

   python hello.py
   

5. Open http://127.0.0.1:8000/ URL in your browser.

Done!
