""" treelib - Python 2/3 Tree Implementation `treelib` is a Python module with two primary classes: Node and Tree. Tree is a self-contained structure with some nodes and connected by branches. A tree owns merely a root, while a node (except root) has some children and one parent. Note: To solve string compatibility between Python 2.x and 3.x, treelib follows the way of porting Python 3.x to 2/3. That means, all strings are manipulated as unicode and you do not need u'' prefix anymore. The impacted functions include `str()`, `show()` and `save2file()` routines. But if your data contains non-ascii characters and Python 2.x is used, you have to trigger the compatibility by declaring `unicode_literals` in the code: .. code-block:: python >>> from __future__ import unicode_literals """ from .tree import Tree # noqa: F401 from .node import Node # noqa: F401
