Perform an example decompilation of python bytecode that performs tree
exploration. The end result should be commented like original code.

Decompiling Python bytecode to source code can be done using tools
like `uncompyle6`. This utility takes compiled Python files (`.pyc` or
`.pyo` files) and translates them back into Python source code.

Let's take an example where we have some bytecode that performs a
basic binary tree exploration (e.g., a simple binary tree traversal).
Unfortunately, I cannot decompile actual bytecode without a `.pyc`
file. However, I can demonstrate what this might look like by
providing a hypothetical example of a binary tree traversal function,
and then showing how it might be commented after decompilation.

Here's an example of simple Python code for binary tree traversal:

```python
class Node:
    def __init__(self, key):
        self.left = None
        self.right = None
        self.val = key


def printInorder(root):
    if root:
        printInorder(root.left)
        print(root.val),
        printInorder(root.right)


def printPostorder(root):
    if root:
        printPostorder(root.left)
        printPostorder(root.right)
        print(root.val),


def printPreorder(root):
    if root:
        print(root.val),
        printPreorder(root.left)
        printPreorder(root.right)
```

If this were to be decompiled without comments, it might look
something like this:

```python
class Node:
    def __init__(self, key):
        self.left = None
        self.right = None
        self.val = key


def printInorder(root):
    if root:
        printInorder(root.left)
        print(root.val),
        printInorder(root.right)


def printPostorder(root):
    if root:
        printPostorder(root.left)
        printPostorder(root.right)
        print(root.val),


def printPreorder(root):
    if root:
        print(root.val),
        printPreorder(root.left)
        printPreorder(root.right)
```

To annotate and comment this decompiled code, one might add
explanations for the functionality of each function and method:

```python
class Node:
    def __init__(self, key):
        # Initialize a new binary tree node with a key value
        # and set left and right children to None.
        self.left = None
        self.right = None
        self.val = key


def printInorder(root):
    # Recursively print the keys of the binary tree in
    # inorder traversal: left subtree -> root -> right subtree.
    if root:
        printInorder(root.left)  # Recur on the left subtree
        print(root.val),  # Print the root node's value
        printInorder(root.right)  # Recur on the right subtree


def printPostorder(root):
    # Recursively print the keys of the binary tree in
    # postorder traversal: left subtree -> right subtree -> root.
    if root:
        printPostorder(root.left)  # Recur on the left subtree
        printPostorder(root.right)  # Recur on the right subtree
        print(root.val),  # Print the root node's value


def printPreorder(root):
    # Recursively print the keys of the binary tree in
    # preorder traversal: root -> left subtree -> right subtree.
    if root:
        print(root.val),  # Print the root node's value
        printPreorder(root.left)  # Recur on the left subtree
        printPreorder(root.right)  # Recur on the right subtree
```

Note that the quality of decompiled code can depend heavily on the
complexity of the original code and the effectiveness of the
decompiler. Sometimes manual intervention is needed to create clean,
readable, and functional source code from decompiled bytecode.
