Certainly! Python allows a recursive _iter_ function, which can be useful in situations where you have a nested or hierarchical data structure, and you want to traverse it in a recursive manner. Let's create a simple example to illustrate this concept.
In this example, we have a simple TreeNode class representing a node in a tree structure. Each node has a value and a list of children. The add_child method is used to add children to a node.
The _iter_ method is where the recursion happens. It yields the current node's value and then iterates over each child, recursively calling _iter_ on each child node using yield from.
When you run the example, it will output:
This demonstrates how the recursive _iter_ function allows you to traverse a nested data structure, in this case, a tree. You can adapt this concept for other recursive data structures as needed.
