Python Tree data structures and tools.
Install forestry with python's pipenv or pip package managers.
$ pipenv install forestry$ pip install forestry>>> t = Tree(key='a', value=1)
>>> assert t['a'] == 1
>>> t.append(key='b', value=2) # Adds a child to the root node by default
>>> assert t['b'] == 2
>>> t.append(key='c', value=3) # Add another child to the root node
>>> t.parent(key='c') == 1 # Ask for the parent of c
>>> t.children(key='a') == [2, 3] # Ask for the children of a
>>> t.append(key='d', value=4, parent='b') # Adds child to b
>>> assert t.ancestors(key='d') == [2, 1]
>>> assert t.path(key='d') == [1, 2, 4] # Traverse from root to node
