There are some minor differences in the object behaviour. See slots_ for any details. .. _slots: https://docs.python.org/3/reference/datamodel.html#slots The only tree relevant information is the `parent` attribute. If `None` the :any:`LightNodeMixin` is root node. If set to another node, the :any:`LightNodeMixin` becomes the child of it. The `children` attribute can be used likewise. If `None` the :any:`LightNodeMixin` has no children. The `children` attribute can be set to any iterable of :any:`LightNodeMixin` instances. These instances become children of the node. >>> from anytree import LightNodeMixin, RenderTree >>> class MyBaseClass(): # Just an example of a base class ... __slots__ = [] >>> class MyClass(MyBaseClass, LightNodeMixin): # Add Node feature ... __slots__ = ['name', 'length', 'width'] ... def __init__(self, name, length, width, parent=None, children=None): ... super().__init__() ... self.name = name ... self.length = length ... self.width = width ... self.parent = parent ... if children: ... self.children = children Construction via `parent`: >>> my0 = MyClass('my0', 0, 0) >>> my1 = MyClass('my1', 1, 0, parent=my0) >>> my2 = MyClass('my2', 0, 2, parent=my0) >>> for pre, _, node in RenderTree(my0): ... treestr = u"%s%s" % (pre, node.name) ... print(treestr.ljust(8), node.length, node.width) my0 0 0 ├── my1 1 0 └── my2 0 2 Construction via `children`: >>> my0 = MyClass('my0', 0, 0, children=[ ...
