Example

A simple tree, with text nodes

from nutree import Tree, Node

tree = Tree("Store")

n = tree.add("Records")

n.add("Let It Be")
n.add("Get Yer Ya-Ya's Out!")

n = tree.add("Books")
n.add("The Little Prince")

print(tree.format())

Tree<'Store'>
├── 'Records'
│   ├── 'Let It Be'
│   ╰── "Get Yer Ya-Ya's Out!"
╰── 'Books'
    ╰── 'The Little Prince'

Tree nodes wrap the data and also expose methods for navigation, searching, iteration, ...

records_node = tree["Records"]
assert isinstance(records_node, Node)
assert records_node.name == "Records"

print(records_node.first_child)

Node<'Let It Be', data_id=510268653885439170>
