Depending on your needs, you may find something like bottle or Flask a better choice then. Django can be scaled down a lot, but it's a full-featured framework at its heart. Bottle is pretty minimal (IIRC it doesn't even come with any templating). Flask is somewhere in between as it bundles Werkzeug (a pure WSGI framework) with Jinja (a template library) with some glue code. I have used Flask in the past but often found myself implementing half of Django anyway, which is why I eventually switched. When I only need a bare API with no database and without templates, I usually go for Bottle these days. If you feel like coding closer to the metal and care more about performance than readability, you might also find Twisted useful. -- http://mail.python.org/mailman/listinfo/python-list

You can pick and chose which parts of django you want to use. You don't need to use any of the Django model stuff. You don't need to use any of the template system. You can tear out all or most of the default middleware. At that point, about all that's left is the route parser and dispatch code. The nice thing about this is that as you incrementally discover which pieces of it you really do need, it's easy to pull them in. That being said, we've made a lot of use of Tornado for small stand-alone web services with just a couple of routes. In retrospect, it's unclear if there's any justifiable argument for why we use both Tornado and Django, other than hysterical raisins. -- http://mail.python.org/mailman/listinfo/python-list

+1 for PostgreSQL. It's faster than MySQL for years now, and is much more seriously featured. If you don't need ACID properties (transactions stuff) you should also give Document-based databases like MongoDB a try. It changed my code life. -- http://mail.python.org/mailman/listinfo/python-list

Re: using python in web applications
Well PyPy is just an implementation of Python among many others (but limited to version 2.7). It is not a web server. If you want to make PyPy interact with a web server (such as nginx) you have to use a special protocol such as WSGI or Fast-CGI. For best performances you can for instance use uWSGI that integrates well with nginx but for this you have to recompile nginx. As you see it's a bit complex, you should read the wikis.

[/troll] I have been trolled. :) For any sort of web-based real-time game, here's two things to avoid: 1) Snoopability and modifiability of crucial data. Everything should be stored on the server, so that if anyone fiddles, all they do is break their own client so it has to reload from the server. 2) Massive waste of resources due to unnecessary frameworks/facilities. I play a lot of Flash games, and right now I'm playing one that has coped poorly with a miniature slashdotting. A spike in popularity resulted in a spike in server lag. I fired up a little packet sniffer, and discovered that every time you do anything in the game, the client makes a new POST request to its server. Why?! It's not that hard to hold a socket connection open! In another context, a similar issue - not a problem as yet (that I know of), but would be if the system were to be slashdotted. A server whose sole purpose is to handle script-instigated requests (using HTTP POST for its transport) sends back a Set-Cookie header with a session id. This implies that the server is holding session data for all these clients that are never going to send that cookie back. The server appears to be IIS with ASP scripts, so presumably stateful sessions are enabled by default, so it's costing memory and processing to hold, then discard, all those useless (and probably empty) session state tags. And presumably many MANY other servers have the same thing. What's YOUR framework doing that you don't need, and how much is it costing you? Yeah, I was trolled bad. :) ChrisA -- http://mail.python.org/mailman/listinfo/python-list
using python in web applications
Hello all: I'm curious if there are some good solutions for using Python in web applications. I'm not feeling particularly masochistic, so I do not want to develop this project in PHP; essentially I'm looking to build a web-based MMO. I know that you can use nginx with Python with servers like Flask, but I'm not really sure how well all of those work. Since this will be a game, I can expect quite a few users; I've already got quite a lot of interest. I don't much care for PHP, but the thing that can be said for it is it's pretty quick. How does Python compare? Are there some solutions (I was told about PyPy today) that would be quicker that I could still use for the web app? I'm also curious what databases are suggested? I've always done most of my work in MYSql, but from what I understand postgresql is becoming more popular to.

Anyways, I have read online that many popular websites use Python for some of their web-based applications (for example, Reddit), and that lead me to wonder how is this done? There are various options, the simplest is using a full blown web framework which simplifies about 90% of the work and you only need to code the logic related to your app. Two of the most popular frameworks are django [1] and turbogears [2]. You can also go more low level by designing your own framework from scratch which is something the bigger shops are doing like youtube. In any case there is a wiki page that you might find useful [3].
