Trees are kind of specialized datastructures; no one type of tree
solves all tree-related problems suitably well.

I think probably the most common need for a tree is implementing a
cache, but most times you're tempted to sort inside a loop you're
better off with a tree.

I've put some time into python trees; most of them are on pypi and at:

and:
