So you're suggesting I somehow execute this code:
python Cookie_setheaders.py
in my script? I presume I'd change "Cookie_setheaders.py" to my file name.
That doesn't make sense to me.

I'm sorry but I'm lost. The page on which you said had the missing line:
http://www.doughellmann.com/PyMOTW/Cookie/index.html
has the following code:

import Cookie
c = Cookie.SimpleCookie()
c['mycookie'] = 'cookie_value'
print c

All of which is in my code. The tutorial gave this printout:

$ python Cookie_setheaders.py
Set-Cookie: mycookie=cookie_value

It also has this code:

import Cookie
import datetime

def show_cookie(c):
    print c
    for key, morsel in c.iteritems():
        print
        print 'key =', morsel.key
        print '  value =', morsel.value
        print '  coded_value =', morsel.coded_value
        for name in morsel.keys():
            if morsel[name]:
                print '  %s = %s' % (name, morsel[name])

which, when I tried it, printed nothing at all. Not a very good tutorial :(

This page
http://webpython.codepoint.net/cgi_set_the_cookie
has the following code:

#!/usr/bin/env python
import time
print 'Set-Cookie: lastvisit=' + str(time.time());
print 'Content-Type: text/html\n'
print '<html><body>'
print 'Server time is', time.asctime(time.localtime())
print '</body></html>'

#!/usr/bin/env python
import time, Cookie
cookie = Cookie.SimpleCookie()
cookie['lastvisit'] = str(time.time())
print cookie
print 'Content-Type: text/html\n'
print '<html><body>'
print 'Server time is', time.asctime(time.localtime())
print '</body></html>'

all of which is included in my code (except for extraneous print
statements). Here again is my code:

#! /usr/bin/python

import string
import cgitb; cgitb.enable()
import MySQLdb
import cgi
import sys,os
sys.path.append(os.getcwd())
from login import login
import datetime, Cookie, random
from particulars import title
from templateFrame import top, bottom
from particulars import myCookie
import time
import fpformat
from sets import Set
from particulars import ourOptions

def cart():
  print '''Content-Type: text/html\r\n
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
'''
  cookie = os.environ.has_key('HTTP_COOKIE')
  if not cookie:
    cookie = Cookie.SimpleCookie()
    cExpires, cPath, cComment, cDomain, cMaxAge, cVersion = myCookie()
    cookie['lastvisit'] = str(time.time())
    cookie['lastvisit']['expires'] = cExpires
    cookie['lastvisit']['path'] = cPath
    cookie['lastvisit']['comment'] = cComment
    cookie['lastvisit']['domain'] = cDomain
    cookie['lastvisit']['max-age'] = cMaxAge
    cookie['lastvisit']['version'] = cVersion
    cookie['mycookie'] = 'mycookie'
    cookieFlag = 'new'
  else:
    cookie = Cookie.SimpleCookie(cookie)
    cookieFlag = 'old'
#  Don't know what to do with this. It's for when client won't accept
cookies
#  sessionDir = os.environ['DOCUMENT_ROOT'] + '/tmp/.session'
#  session = shelve.open(sessionDir + '/sess_' + sid, writeback=True)
#  session['lastvisit'] = repr(time.time())
#  session.close()
  print cookieFlag
  cookie.load(cookie)
  print cookie
 ...

Please advise.
TIA,
beno
