btr is a Python module that provides an interface to the binary tree based on the red-black tree implementation.
You can install btr using pip
:
pip install btr
To start using btr, import the RedBlackTree
class:
from btr import RedBlackTree
To create an empty tree, simply call the constructor:
tree = RedBlackTree()
To add elements to the tree, use the add
method:
tree.add(42)
tree.add(13)
tree.add(27)
To remove elements from the tree, use the remove
method:
tree.remove(13)
tree.remove(42)
To search for an element in the tree, use the contains
method:
if tree.contains(27):
print("Element found!")
else:
print("Element not found.")
Each node in the tree is represented by an instance of the Node
class, which has two attributes: left
and right
, which represent the left and right child nodes, respectively. The Node
class can be subclassed to store additional attributes for the elements being stored in the tree.
btr provides a reliable and efficient implementation of a red-black tree in Python. Its balanced tree structure and logarithmic time complexity for insertion, deletion, and search operations make it an excellent choice for a variety of applications.
