Data Structures in Python - Trees
Article Introduction：A tree data structure in Python is a non-linear data structure in which elements (called nodes) are connected by edges, with only one path between any two nodes.
Tree data structure in Python
Like all programming languages, a tree in Python is a hierarchical data structure with each node connected by edges. A tree consists of multiple nodes with a unique root node as the starting point. Trees are often used to represent hierarchical organizations, such as organizational charts or file systems.
The topmost node of the tree is called the root node, and the nodes below it are called child nodes. Each node can have multiple child nodes, and these child nodes can also have their own child nodes, forming a recursive structure.
Basic terminology for trees
Root node: The top node of the tree.
