# skbio.tree.TreeNode.postorder¶

TreeNode.postorder(include_self=True)[source]

Performs postorder iteration over tree.

State: Experimental as of 0.4.0.

This is somewhat inelegant compared to saving the node and its index on the stack, but is 30% faster in the average case and 3x faster in the worst case (for a comb tree).

Parameters

include_self (bool) – include the initial node if True

Yields

TreeNode – Traversed node.

Examples

>>> from skbio import TreeNode
