Description:
littletree 0.8.1
LittleTree is a library that provides a tree data structure to python,
which is both fast and flexible.
It can be used to represent file systems, taxonomies and much more.
Features
Intuitive basic creation and modification of trees.
Efficient implementation of common tree operations and traversals.
Works on trees that are 10 000 layers deep.
Extensible. Subclass from BaseNode if you need more freedom.
Can be imported / exported to many different formats (nested dict, rows, relations, graphviz, mermaid, newick, networkx).
Purely written in Python.
Limitations
Each node has at most one parent. (It's a tree not a graph!)
Nodes cannot be their own ancestor.
Installing
Use pip to install littletree:
$ pip install --upgrade littletree
Usage
A tree can be used in a similar way as a dict:
from littletree import Node
tree = Node(identifier="World")
tree["Asia"] = Node()
tree["Africa"] = Node()
tree["America"] = Node()
tree["Europe"] = Node()
# Print tree to console
tree.show()
# Show tree as an image
tree.to_image().show()
The resulting tree is printed like this:
World
├─ Asia
├─ Africa
├─ America
└─ Europe
If Pillow and graphviz are installed,
it will also display the following image:
