If I understand you correctly, something like this is what you want:

import cgi
form = cgi.FieldStorage()

Then you can use form as you would a dictionary with key/value pairs:

if form.has_key("edit"):
    if form["edit"].value == "add":
        add_node()
    elif form["edit"].value == "delete":
        delete_node()

http://url/script?edit=add would then cause the function add_node() to run.
