Best way to create a simple python web service


Question

I've been using python for years, but I have little experience with python web programming. I'd like to create a very simple web service that exposes some functionality from an existing python script for use within my company. It will likely return the results in csv. What's the quickest way to get something up? If it affects your suggestion, I will likely be adding more functionality to this, down the road.

Have a look at werkzeug. Werkzeug started as a simple collection of various utilities for WSGI applications and has become one of the most advanced WSGI utility modules. It includes a powerful debugger, full featured request and response objects, HTTP utilities to handle entity tags, cache control headers, HTTP dates, cookie handling, file uploads, a powerful URL routing system and a bunch of community contributed addon modules.

It includes lots of cool tools to work with http and has the advantage that you can use it with wsgi in different environments (cgi, fcgi, apache/mod_wsgi or with a plain simple python server for debugging).

web.py is probably the simplest web framework out there. "Bare" CGI is simpler, but you're completely on your own when it comes to making a service that actually does something.

"Hello, World!" according to web.py isn't much longer than an bare CGI version, but it adds URL mapping, HTTP command distinction, and query parameter parsing for free:

import web

urls = (
    '/(.*)', 'hello'
)
app = web.application(urls, globals())

class hello:        
    def GET(self, name):
        if not name: 
            name = 'world'
        return 'Hello, ' + name + '!'

if __name__ == "__main__":
    app.run()
