st invented a cute ;-) two-liner using list comprehensions:
# alist = list above
tmp, dk = [], {}
[(x.startswith('VLAN') and (dk.setdefault(x,[]) or tmp.append(x))) or
(not x.startswith('VLAN') and dk[tmp[-1]].append(x))for x in alist
if x != 'Interface']
No need to use a nuke like itertools to kill a fly. ;-)

A positive proof that you can write perl code in Python. I, for
instance, have had my brain warped by C and tend to write C-like code in
Python. That's only half a joke, sadly. I'm trying to change my habits
but it's hard.

It does, in fact I was wondering why my iterator didn't work until I
figured issubclass(bool, int) is true.

'], ['python'], ['list'], ['isnt',
'tins'], ['stop', 'post']]
However, when I change the last line to:
print map(list, map(itemgetter(1), gb))
It stops working:
[[], [], [], [], [], [], [], [], [], [], [], [], [], [], [], ['post']]
Why? I was under impression that the only difference between map and
imap is that imap returns iterator allowing to produce a list, while map
returns equivalent list?

as experience with them?
Now, I do now about NLTK and Python bindings to UIMA. The thing is, I do
not know if those are good for the above task. If somebody has
experience with those or other and would be able to say if they're good
for this, please post.

d accomplish this with something similar to the following:
new_dict = {}
for x in MAPPING_DICT.keys():
if x in my_dict.keys():
new_dict[MAPPING_DICT[x]] = my_dict[x]
Although there is probably a better solution to the problem your
having. Perhaps more details could help us lead in you the right
direction?

Thats exactly why I did an explicit check in my post, so as to make
sure that such a collision could not occur. It would seem that
something along what I posted would be safer, if less elegant, than
the others.
