My C++ lecturer used to tell us "'C++ or Java?' is never the question.
For that matter, Java is never the answer."
As for python and cgi, it's pretty simple. Instead of a .php file to be
handled by the php-handler, you have a .cgi file which is handled by the
cgi-handler. Set the action of your html form to the .cgi file. At the
top of the .cgi file, you'll need a line like:
Which tells it to use python as the interpreter. You'll need a few imports:
import cgitb; cgitb.enable() # for debugging - it htmlises
# your exceptions and error messages.
print """Content-type: text/html; charset="iso-8859-1";\n"""
# You need that line or something similar so the browser knows what to
do with the output of the script.
Everything that's printed by the python script goes straight to the
client's browser, so the script will have to print html. The cgi module
handles form data, typically formdata = cgi.FieldStorage() will be
filled when a form is sent to the script. print it and see what's in it.
From here, there's a huge number of tutorials on python and cgi on the
web and I'm tired.
Best of luck,
