Can I compile Python for the web?

[Charles]

Dear sirs,

I'm doing some investigations on the Python language.
I'd like to know if it is possible to compile Python code made for the web
(an online database for instance), and to run it using mod_python. How is
it possible? I think it would be very fast to execute the code if it were
compiled.
Thanks,

Python code is already compiled, specifically to .pyc files, though this
is clearly not what you meant by the above. (The .pyc files contain
"bytecode" which is executed by the Python virtual machine, much like a
CPU executes its native opcodes, or like Java executes its own bytecode
instructions.)

What you appear to be asking is if it's possible to create *native
machine code* from Python source in order to achieve a significant
increase in performance. The short answer is "no, not really", and
longer answers include "yes, sort of, using something like Psyco", and
"who cares because it wouldn't give you much better performance for a
web-based application where you're probably either I/O-bound or limited
by the speed of the non-Python database solution you are using in the
first place?".

All pretty true of course, but I think I did read about some tests of
running Zope with psyco. Zope uses a pretty massive amount of Python
code on each access, so there's probably a lot to optimize. Unfortunately
I don't remember what the results were.

But I'd recommend search the zope-user mailing list archives or just
google for "psyco site:zope.org"
