I want to make a Python script available as a service on the net. The script, which is my first ‘proper’ Python program, takes a txt file as argument and writes an image into the work directory. So:
- How difficult is it for somebody who is new to Python and web development?
- How much work is it?
- Do I need a framework (Django, cherryPy, web2py)?
- Are there good tutorials?
- How do I avoid the server to be compromised?
-
What are my next steps?
==> What is the easiest way?
In the end it is enough, if it is a white page, with some text, and a button, which when clicked, opens a file dialog. After the txt is processed, the server should just return the image, which was written on the hard drive. Already I have access to a server which has Ubuntu installed through a friend.
[update]
Thanks for all your answers. After reading them I want to stress again, that I want to have it as minimal as possible. Srikar’s suggestion sounds like the easiest one:
Put it in executable directory of your OS (commonly known as CGI
path). Provide a simple HTML form & upon form submission hit this
script which executes & returns back the image you want to display.
Any objections or comments? Do you know any tutorials for that?

I found this SO answer: File Sharing Site in Python Is this a sensible approach?
In the end, I created what I needed with Flask.
They have a well documented pattern / tutorial on Uploading Files. The tutorial is understandable even for people with little python and web expericence.
To get a first working version it took me 2h and the resulting code was only 50 lines. This includes, starting the webserver, having a html file/form with file upload and serving a file back to the user.
