Python web frameworks

[joe jacob]

There are a lot of web frameworks for python like django, mod_python,
spyce, turbo gears, Zope, Cherrypy etc. Which one is the best in terms
of performance and ease of study.

The only one that I have used extensively is Django, which is very
easy to use and quite powerful in the arena for which it was created.
It has a powerful admin interface that automatically generates data
entry forms for content producers and a decent template system. It
has some definite drawbacks, though. The admin interface is difficult
to customize because it was not meant to be customized too much
(Django was written in a newspaper environment, where data needs to go
online quickly and be easily customizable for the next story or next
year's use). It also lacks ajax support.

I understand that Zope has a pretty high learning curve and is
currently in various stages of rewrite.

I don't know much about the others. Turbo gears uses Mochikit, which
hasn't had a new stable release in some time. I prefer jQuery myself.

I wouldn't classify mod_python as a web framework: "Mod_python is an
Apache module that embeds the Python interpreter within the server.".

I haven't used all of the frameworks that you have mentioned, but I
really like what I have seen from Pylons so far.

Pylons too, it's good for development but using the bundled web server
is not recommended for production.

I'm making web apps with CherryPy at work and it's quite good.
the official docs are a bit messy though but they left useful comments
in their code.

12/7. Django comes with its own little server so that you don't have

to set up Apache on your desktop to play with it.

I was rather shocked to learn that django only has this tiny server and does
not come with a stand-alone server and is supposed to run as
mod_python/cgi-driven app through apache.

Which reaps you of all the benefits of standalone servers like connection
pooling & caching data and so forth. Including sessions - I presume they
always go into the db/filesystem as PHP does.

You can use jQuery with TurboGears if you develop custom widgets (I do so).
No problem here.

The standalone server aspect of a large number of Python Web
frameworks typically involves BaseHTTPServer from the standard
library, as far as I've seen, excluding things like Twisted which
aspire to offer production quality server solutions themselves. This
was common back in the old days of Webware, in contrast to Zope which
used Medusa at the time, if I remember correctly.

Which reaps you of all the benefits of standalone servers like connection
pooling & caching data and so forth. Including sessions - I presume they
always go into the db/filesystem as PHP does.

I guess it's a compromise between deployment complexity and benefits
in the above areas, although mod_python should offer some relief in
some of the above areas. What people didn't like about Webware so much
was that run in the recommended way - with a standalone server which
communicated with Web server processes - people had to have separate
long-running processes, which various hosting providers didn't like.

What's most important is that you should be able to switch out one
server technology with another when you reach the limits of the
original, all without having to rewrite your application or do some
major re-plumbing. It does surprise me that mod_python is recommended
for use with Django in the various quick start guides I've read, but I
suppose that lets the developer avoid the issue of migrating up from a
simple server to something more scalable. Not that this should be a
problem, of course.

As far as I'm concerned, the winners are Django and Pylons (my own
preference going to Pylons).

Alas it is even worse than that, the development server is single
threaded and that can be a big problem when developing sites that make
multiple simultaneous requests at the same time (say if one of those
requests stalls for some reason). It is trivial to add multi threading
via a mixin (takes about two lines of code) but it does not seem to be
a priority to do so.

For large traffic though, Django is better than just about anything
other framework because it is built as multiprocess framework through
mod_python (rather than threaded). So there is no global interpreter
lock, thread switching etc. Django was built based in a real life
heavy duty use scenario, and over the years that really helped with
ironing out the problems.
