I don't know what's meant by that |_> symbol. If it's really supposed
to be like subdirectories, there'd be a name associated with the
sublist. In which case you'd probably want dicts, not lists.
So I'd have to guess you want something like:
["head", ["neck", ["arms", ["legs"]]]]
To turn your list into that one, I'd write something like (untested):
def chop_up(mylist):
if len(mylist) == 1:
return mylist
return [mylist[0], chop_up(mylist[1:])]
I suspect your real problem is totally different, but this was an
interesting exercise.
