John--
Thanks again - I so appreciate your direction!
Okay so i have a list of lists just as you describe below...I hate to make
myself look really stupid...but I don't see how this converts to a tree
structure...I was looking at this earlier and I guess what's confusing me
are the duplicates...do I need to convert the list below into a data
structure of tuples? Can this be plugged straight into a tree control?
Now my question is:
How do I get from here:
[('north america', 'United States', 'California'),
('north america', 'United States, 'Texas'),
('north america', 'United States, 'Washington'),
('north america', 'Canada', 'Ontario'),
('Asia', 'Japan', None),
To Here:
geo=[("north america", [
("united states",[
("california", []),
("oregon", []),
("arizona", [])]),
("canada", [
("Ontario", [])])]),
("asia", [
("japan", [])])
