Hi Lauren,
Basically, there is no way to do that because your lists don't contain
any information about which coutries corerspond to which continents,
et cetera.
>From looking at your other email, my guess is that you want to start
with SQL looking something like this:
select continent, country, state from world_globe
with the intention of getting back data that looks like:
[('America', 'United States', 'California'),
('America', 'United States, 'Texas'),
('America', 'United States, 'Washington'),
('America', 'Canada', 'Ontario'),
('Asia', 'Japan', None),
# etc
]
It would be fairly straightforward to take data looking something like
that and produce a tree.
