So you want the advantages of Python, but none of the trade-off's. Well
wouldn't we all?
You would have to write test for your app to test this. But they should
be roughly in the same ballpark.

I don't know about sessions, but my guess is that there is something out
there. cookies, get and post's can be handled nicely by the cgi module.

try/except works like a charm for this. Use it myself.

smtplib is your friend. Not quite as friendly as some email packages.
But together with the email module it is very powerfull

It is not quite clear what you mean here. But if you want to send a file
from your server to another webserver/form, you just use urllib/urllib2.
If you want to receive files on your server it is built into the cgi module.

Doesn't Apache do this?

Pythons regexp's are probably as powerfull as any. Se the re module.

hmmm! Don't know about this one. Python isn't embedded like that out of
the box. Should be pretty easy to write a function wich does something
like it though.

Use the Borg pattern:
