I just started learning Python, and I'm trying to figure out how to access GET/POST form variables. Anyone know? Thanks.

With... raw sockets? CherryPy? CGI?

That sounds sorta complicated. Isn't there an easy way to do it? In PHP you can use $_GET['var'] or $_POST['var']...

EDIT: I believe this article covers what I was looking for.

No... I was asking you what the medium was for attaining the arguments? Are you trying to do it

I take it from that tutorial that you were using CGI. Just stick with a tutorial then, not much more to say. Good luck.

I'm talking about getting information submitted to a script by an HTML form. If there's an easier/better way to do it than by using the CGI module, I'd be glad to hear about it.

I know that's what you're talking about, but it would have helped if you said what you're listening to the HTTP packets with. CherryPy, for example, makes this very easy for you. The POST/GET arguments come in directly as arguments to the functions you map to pages. http://cherrypy.org can teach you all about CherryPy.

Raw Sockets you would have to parse yourself. Not sure about CGI. Not aware of any other methods, other then the HTTP module that interfaces to the socket library.

CGI module is the way to go. Its not too hard, very similiar to PHP besides the import statement.

CGI is the way to go only if you have no alternative. If your host restricts you to Python CGI, then that's what you have to use. If you have no such restriction, I can think of absolutely no advantage of using CGI.

CGI is the only alternative I have on my commercial host. I find it straightforward. Here's some snips:

(Toggle Plain Text)

print "Content-type: text/html\n\n"
import os
import cgitb; cgitb.enable()  #Debug aid to be removed later
import cgi
import re
import types
...
...
SERVER = os.environ
script = SERVER ['SCRIPT_NAME']
query = SERVER ['QUERY_STRING']
browser = SERVER ['HTTP_USER_AGENT']
ip = SERVER ['REMOTE_ADDR']
...
...
form = cgi.FieldStorage ()
page = form.getfirst ("page", "0-0")
...

That last statement gets the page field from the form or from a GET like "myurl?page=0-0&blah=blah". It gets the first, if there are more than one, and returns the second argument as a default if it isn't present.

Thanks DaWei.

Why is CGI so bad? Would you suggest using CherryPy like Sane?
