At least as far as I can tell, tho, Python as a CGI scripting engine isn't
as versatile as Perl.
Now, lemme quantify that: I set up mod_python per the instructions, and
from everything that I've learned as a beginner at Python & a fairly
knowledgeable Linux geek & web admin, Apache's configuration of mod_python
only sets a single named script as a viable python CGI program, or if there
is a way of having multiple python CGI scripts in one config, there's /no/
documentation as to how to set that up.
If you tell Apache that you want script.py as your CGI, that's all you get.
If you can tell Apache that *.py should all be run, Google can't find it,
and every "wildcard" permutation I've tried in my httpd.conf file resulted
in Apache barfing & refusing to start.
What do I do when I want a guestbook.py, a forsale.py & wantlist.py?
Usually code it in Perl or ColdFusion.
Oh, and WRT your mention of lack of security in a lot of perl CGIs out
there -- I do agree, but setting up a wildcard *.cgi to run from a non-CGI
directory is a big security hole in itself, so that's why I wanted another

To each his own. I'm constantly amused by people who are amazed that not
everyone fits into their worldview. I personally much prefer /stated/ loop
boundries (while/wend; if/else/endif; for/next) but braces aren't a problem
either -- and I'll be the first to admit that the indentation is less
difficult than I'd thought to become accustomed to (well, once I reconfiged
my editor to quit converting spaces to tabs...)
I can honestly say that it took me no less time to start hacking usable
proggies in Perl than it did in Python. Admittedly, I had better
documentation for Perl, so that's a testament to Python, but I've also got
8 more years of experience under my belt, and hacking an unknown language
in many ways has gotten easier... Flip a coin...
I'm not giving up on Python (as I have with PHP...) but personally, I don't
think that mod_python is quite ready for prime-time as a CGI scripting
mega-powerhouse. I honestly hope that this changes soon, and when it does,
I will switch! But until then, I just can't put Perl on the back burner...
