Below is a complete python file that constructs the tree as per your specification and prints it out. This code snippet includes the `Node` class definition you provided and then constructs the tree structure according to the given representation `(1 (2 (3 4 5 6) (7 8)) (9 10 (11 12)))`. Finally, it prints the tree by casting the `root` node to a string using `str(root)`.

To achieve the task, we'll start by defining the `Node` class as provided. Then, we will create the tree structure as described, by instantiating `Node` objects and linking them appropriately. We'll then print out the tree by converting the root node to a string. Here's how the complete Python file would look:

To create and print the tree as specified, you'll need to follow these steps: 1. Define the `Node` class as provided. 2. Create the root node and subsequently create all other nodes as children of their respective parent nodes according to the tree structure given. 3. Print the `root` node by converting it to a string using the `str()` function, which will implicitly use the `__repr__` method of the `Node` class. Here is a complete Python file that accomplishes this:
