Powerful and Lightweight Python Tree Data Structure..
Project description
Documentation
The Documentation is hosted on http://anytree.readthedocs.io/en/2.5.0/
Getting started
Usage is simple.
Construction
>>> from anytree import Node, RenderTree >>> udo = Node("Udo") >>> marc = Node("Marc", parent=udo) >>> lian = Node("Lian", parent=marc) >>> dan = Node("Dan", parent=udo) >>> jet = Node("Jet", parent=dan) >>> jan = Node("Jan", parent=dan) >>> joe = Node("Joe", parent=dan)
Node
>>> print(udo) Node('/Udo') >>> print(joe) Node('/Udo/Dan/Joe')
Tree
>>> for pre, fill, node in RenderTree(udo): ... print("%s%s" % (pre, node.name)) Udo ├── Marc │ └── Lian └── Dan ├── Jet ├── Jan └── Joe
>>> from anytree.exporter import DotExporter >>> # graphviz needs to be installed for the next line! >>> DotExporter(udo).to_picture("udo.png")
Manipulation
A second tree:
>>> mary = Node("Mary") >>> urs = Node("Urs", parent=mary) >>> chris = Node("Chris", parent=mary) >>> marta = Node("Marta", parent=mary) >>> print(RenderTree(mary)) Node('/Mary') ├── Node('/Mary/Urs') ├── Node('/Mary/Chris') └── Node('/Mary/Marta')
Append:
>>> udo.parent = mary >>> print(RenderTree(mary)) Node('/Mary') ├── Node('/Mary/Urs') ├── Node('/Mary/Chris') ├── Node('/Mary/Marta') └── Node('/Mary/Udo') ├── Node('/Mary/Udo/Marc') │ └── Node('/Mary/Udo/Marc/Lian') └── Node('/Mary/Udo/Dan') ├── Node('/Mary/Udo/Dan/Jet') ├── Node('/Mary/Udo/Dan/Jan') └── Node('/Mary/Udo/Dan/Joe')
Subtree rendering:
>>> print(RenderTree(marc)) Node('/Mary/Udo/Marc') └── Node('/Mary/Udo/Marc/Lian')
Cut:
>>> dan.parent = None >>> print(RenderTree(dan)) Node('/Dan') ├── Node('/Dan/Jet') ├── Node('/Dan/Jan') └── Node('/Dan/Joe')
Installation
To install the anytree module run:
pip install anytree
If you do not have write-permissions to the python installation, try:
pip install anytree --user
