lxtree
Package to draw tree structures (tree linux command style)
Basic usage
Build the tree structure using TreeNode
s. A TreeNode
can contain other TreeNode
s
to represent the tree. When builded you car get a string representation of it,
or get string of a sub-tree using some child as root.
Code samples
from lxtree import TreeNode # Creating root root = TreeNode('root') # Adding a list of nodes root.children = [TreeNode('branch1'), TreeNode('branch3')] # Insert node root.insert_child(TreeNode('branch2'), 1) # Appending to a branch 1 by index root[0].append_child(TreeNode('branch11')) # Using index to assign children to branch11 root[0][0] = [TreeNode('leaf111'), TreeNode('leaf112')] # Use `set_children` to add nodes as argv root[1].set_children(TreeNode('leaf21'), TreeNode('leaf22'), TreeNode('leaf23')) # Print tree print(root)
Creating all structure at once
root = TreeNode('root').set_children( TreeNode('branch1').append_child( TreeNode('branch11').set_children( TreeNode('leaf111'), TreeNode('leaf112') ) ), TreeNode('branch2').set_children( TreeNode('leaf21'), TreeNode('leaf22'), TreeNode('leaf23') ), TreeNode('branch3') ) print(root)
Creating the tree from a dict
tree_data = { 'root': { 'branch1': { 'branch11': { 'leaf111': None, 'leaf112': None } }, 'branch2': { 'leaf21': None, 'leaf22': None, 'leaf23': None }, 'branch3': None } } print(TreeNode.tree_from_dict(tree_data))
