first attempt - myjar has no attribute 'value'
second attempt -
re:
myjar = cookielib.CookieJar()
for cookie in myjar:
print cookie.value
In this case the above code should print a single 'B'.
This does work. However, it only ever returns me one value. For
instance, the first three are BZh. My code is:
def urlsearch(times):
x = 12345
count = 0
myjar = cookielib.CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(myjar))
while count < times:
param = urllib.urlencode({'busynothing': x})
z =
opener.open("http://www.pythonchallenge.com/pc/def/linkedlist.php?%s";
% param)
text = z.read()
lister = string.split(text)
x = lister[-1]
count = count + 1
return myjar
Now, if I'm using the jar the way I think I am, I'm creating it
outside the while loop, and then when I use the opener within the
while loop (to open each successive url), I should be adding a new
cookie, right? so that I have a jar full of multiple cookies? But it's
acting like it's just *replacing* the old cookie with the new one,
because when I'm done with that function, I do:
jar6 = urlsearch(2)
for cookie in jar6:
print cookie.value
(2 is number of times)
If I do urlsearch(1), I get B for the value (as expected). If I do
urlsearch(2), I get Z (and only Z. Not BZ). Ditto urlsearch(3), I get
h (and only h, not BZh).
Is it truly replacing the old cookie with the new one? That isn't what
I want to do, and not how I would think a cookie jar would work. Am I
setting it up incorrectly?

This seems perfectly rational to me. However, having the
"cookie.value" part used in an actual example would have been very
helpful.

I assumed that a cookie jar would work kind of like a list. I could
add new cookies to it at each step of my while loop, and then iterate
over the "list" of cookies to get out the pieces of info I wanted. I'm
hoping this is correct, because that's how I *want* to use this cookie
jar!

Yeah, it was kind of confusing why it was called an "item" in one
version and a "value" in another. But then, most things are confusing
to me ;)

I'm looking at the cookielib page - why can't I find .deepvalues()?
It's funny to me, but some of these documentation pages I find exactly
what I'm looking for, including examples, and can immediately put it
to practical use in my code. Some of the libraries I read a hundred
times and can never seem to find what I'm looking for.
In any case, if anyone has any ideas why my cookiejar isn't collecting
a bunch of cookies but instead only returning the last one, I'd be
very grateful!
Thanks again for all your help and suggestions.
