Are cookie jars files known to be large?
I was perplexed by this too when I did the challenge Denise is on. Your question prompted a look at the cookielib source. It turns out that iterating over the CookieJar is actually doing a recursive tree walk of the contents of the CookieJar. This only pushes the mystery one step back, though - the attribute of the Cookie that is recursively iterated is called 'item', but the Cookie class defined in cookielib has no attribute 'item'. Take a look at cookielib.deepvalues() if you are curious. Kent _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
