[Tutor] Strange Question

[Liam Clarke]

Hi,

It's certainly doable in Python; but as Danny said, you'll want a
handle on Python before you launch into web frameworks.

However, Python's a pretty easy language to pick up and run with.Just
make sure you use a Python aware editor. Going by your email address,
I found Vim to be pretty good with Python, once I figured out how to
do folding. So much so, that I downloaded gVim for my windows box.

If you're an Emacs guru, then I'm sure you'll be fine. :-)

With regard to #7 -

   7. The Python code (cgi script?) calls another application (server
resident) that performs processing on the graphics file.

You could actually do this within your Python code if you wanted, with
the Python Imaging Library - http://www.pythonware.com/products/pil/

You may already have a suitable external app in mind, but I thought
I'd mention it just in case.

With regards to Python web frameworks, Django and Turbogears are the
two front-runners, as Danny mentioned. Django is the more mature of
the two, but Turbogears is pretty good as well, both have helpful
Google Groups/mailing lists.

I'm not hugely experienced in Python, but I managed to get up and
running okay with both. It's easier to get Django working with Apache
than Turbogears. Turbogears uses the Kid templating language, but can
also use other templating languages like Cheetah. Turbogears is 4
separate packages combined, Cherrypy, SQLObject, Kid and Mochikit.

Beyond that, I'm not too sure. I'm playing with Django at the moment,
Turbogears 0.9 is still in alpha, last time I checked, which means a
bit of tweaking of conf files to get working with mod_python, if
you're familiar with Apache at all, and as I'm a Windows monkey, I
find it a bit daunting, so hence Django, as it plays nicely. :)

Good luck and I look forward to questions to this list. :)

Regards,

Liam Clarke
