Package: typed-tree
TypedTree by Brett KromkampContextualise, a knowledge management application that I am currently developing, allows the user to visualise their topics of interest (that is,nodes) and the relationships between those topics (that is,references to other nodes) using a network graph visualisation. To that effect, TypedTree makes it straightforward to not only enable the visualisation of the actual (network) graph itself but also to enhance the visualisation with information related to the type of each node and the references to other nodes, respectively.TypedTree is based on an earlier implementation of mine:Python tree implementation.InstallationTypedTree officially supports Python 3.7–3.10. To install TypedTree, simply:$ pip install --upgrade typed-treeInstall the Development VersionIf you haveGitinstalled on your system, it is possible to install the development version of TypedTree.Before installing the development version, you may need to uninstall the standard version of TypedTree usingpip:$ pip uninstall typed-treeThen do:$ git clone https://github.com/brettkromkamp/typed-tree
$ cd typed-tree
$ pip install -e .Thepip install -e .command allows you to follow the development branch as it changes by creating links in the right places and installing the command line scripts to the appropriate locations.Then, if you want to update TypedTree at any time, in the same directory do:$ git pullExamplefromtypedtreeimportTraversalModefromtypedtreeimportTreetree=Tree()# A node without a parent pointer is by definition the root nodetree.add_node('Elon Musk',node_type='person')tree.add_node('Lyndon Rive',parent_pointer='Elon Musk',node_type='person',edge_type='family')tree.add_node('SpaceX',parent_pointer='Elon Musk',node_type='company',edge_type='founder')tree.add_node('Tesla',parent_pointer='Elon Musk',node_type='company',edge_type='founder')tree.add_node('Solar City',parent_pointer='Lyndon Rive',node_type='company',edge_type='co-founder')tree.add_node('Solar Energy Services',parent_pointer='Solar City',node_type='product',edge_type='service')tree.add_node('Falcon 9',parent_pointer='SpaceX',node_type='rocket',edge_type='technology')tree.add_node('Falcon Heavy',parent_pointer='SpaceX',node_type='rocket',edge_type='technology')tree.add_node('Dragon',parent_pointer='SpaceX',node_type='space-ship',edge_type='technology')tree.add_node('Model S',parent_pointer='Tesla',node_type='car',edge_type='product')tree.add_node('Model X',parent_pointer='Tesla',node_type='car',edge_type='product')tree.add_node('Model Y',parent_pointer='Tesla',node_type='car',edge_type='product')tree.add_node('Roadster',parent_pointer='Tesla',node_type='car',edge_type='product')print('\n***** TREE STRUCTURE *****')tree.display('Elon Musk')print('\n***** DEPTH-FIRST ITERATION *****')fornodeintree.traverse('Elon Musk'):print(f"{node.identifier}[{node.typeor'*Undefined*'}]")print('\n***** BREADTH-FIRST ITERATION *****')fornodeintree.traverse('Elon Musk',mode=TraversalMode.BREADTH):print(f"{node.identifier}[{node.typeor'*Undefined*'}]")Output***** TREE STRUCTURE *****
