pip install sutree

This package includes two libraries:

• Tree library.
• Tree display library.

TODO feature: Implement B-Tree.

Tree library:

• Two types of trees: Binary Search Tree, AVL Tree.
• Regular operations:
  • Checking empty.
  • Getting number of nodes.
  • Getting height.
  • Traversal:
    • 3 options: pre-order, in-order, post-order.
    • 2 modes: recursive traversal and non-recursive traversal.
  • Checking existence of a key.
  • Getting minimum key.
  • Getting maximum key.
  • Insertion.
  • Removal.
  • Constructing from a list.

Tree display library:

• It can config space between 2 branch neighbors.
• It can config precision of floating-point numbers.
• It accepts any type of key of node. Just makes sure key is convertible to string.
• It accepts any structure of node, which is high flexibily.
• It can config left margin.
• It outputs to:
  • a string, or...
  • a list of rows.

There are two sections of tutorials:

• Tree: Using pre-defined trees in library such as BinaryTree, AvlTree...
  • Take a look at /test/tree_.
• Display: Display a tree.
  • Read tutorials_display.md

Update later.

• Language: Python 3.8
• Paradigms: object-oriented, procedural
