This Python code illustrates a binary tree example representing the family tree of Hamlet the Piglet. The family tree consists of nodes representing piglets, with each piglet having a left and right child node.
- The
Node
class represents a node in the binary tree. - Each node contains references to its left and right child nodes and a
Piglet
object. - The
insert
method inserts a new piglet into the family tree in the appropriate position based on the piglet's name. - The
list_family
method lists the family members in a hierarchical representation using in-order traversal.
- The
Piglet
class represents a piglet in the family tree. - Each piglet has a name and can speak to another piglet.
- Create a
Piglet
object for the root of the family tree. - Initialize a
Node
object with the rootPiglet
. - Add more piglets to the family tree using the
insert
method. - Visualize the family tree using the
list_family
method.
hamlet = Piglet("Hamlet") root = Node(hamlet)
Add more piglets to the family tree petunia = Piglet("Petunia") babe = Piglet("Babe") wilbur = Piglet("Wilbur")
root.insert(petunia) root.insert(babe) root.insert(wilbur)
Visualize the family tree print("Family Tree:") print(root.list_family())
In the list_family
method, the 'r' and 'l' stand for 'right' and 'left' respectively. They indicate the side of the parent node where the current node is located in the binary tree.
