I am a beginner in python. For practice reasons I want to learn how to upload a python code to a website.
I have a domain and web hosting service, however I’m really confused about how to integrate my code with a
web page on my website.

(I have a decent bit of knowledge with Tkinter)
Can anybody show me how to upload this simple function to my website?:
There are two entries on the interface for the user to enter two numbers. On pressing a button a new
window(web page) with the answer displayed.

Thank you.

    The Basics

    Here is a very simple server-side Python script. To use it, put it in your cgi-bin folder on your server. (It can later be configured to run elsewhere, but cgi-bin usually works out of the box.) Then change the permissions on the file via chmod or some Gui control. You need to allow anyone to execute it, so 755 will do. Then navigate to http://domain.tld/cgi-bin/myscript.py.

    #!/usr/bin/python

print "Content-type: text/html"
print
print "<pre>"
import os, sys
from cgi import escape
print "<strong>Python %s</strong>" % sys.version
keys = os.environ.keys()
keys.sort()
for k in keys:
    print "%s\t%s" % (escape(k), escape(os.environ[k]))
print "</pre>"

    If that works you can move on to running more complicated scripts, using frameworks (like web.py), and responding to forms.

    Form Data

    To answer the actual question, we need a page with a form. I made this from a template I use and added a form with a singe input field.

    <!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Webpage</title>
  <meta name="description" content="html5 webpage">
  <meta name="author" content="">
  <!--[if lt IE 9]>
  <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script>
  <![endif]-->
</head>
<body>
    <form action="/cgi-bin/test.py">
    <input name="mystuff" width="500px" />
    <input type="submit" value="Do" />
    </form>
</body>
</html>

    Notice it’s pointing to our test.py script. That needs to be updated too so it understands our mystuff form element. We throw in some error handling and import our cgi modules. The except part is lazily done, but since you won’t use that part of the code, I don’t think it’s that important.

    print "Content-type: text/html"
print
print "<pre>"

import os, sys
import cgi, cgitb
cgitb.enable()

form = cgi.FieldStorage()

try: 
    num = int(form['mystuff'].value)
    print 'The number %d to the 13th power is %d.' % (num, num**13)
except Exception: 
    print 'What am I suposed to do with that?  This is what you call an "err
or message".  Try a number instead'

print "</pre>"

    You should be able to go to your web-page and enter 7 in the field, which will result in a page containing…

    The number 7 to the 13th power is 96889010407.

    Hope that helps.
