Notes

Nodes are ordered by a postorder traversal of the tree. The order is consistent between calls.

If self is a tip, it won’t be yieled unless include_self is True.

Examples

>>> from skbio import TreeNode
>>> tree = TreeNode.read(["((a,b)c,(d,e)f);"])
>>> print(tree.ascii_art())

          /c-------|

          \f-------|
                    \-e
