Thank you for providing your code. It looks like there may be a syntax error in your code. The last line is missing a closing parenthesis. It should look like this:

def printdiff(original_node, updated_node):
    return (
        "".join
            difflib.unified_diff(original_node.splitlines(1), updated_node.splitlines(1))
        )
    )
)

Is there anything else I can help you with?
