# Example usage
planner = SmartPlanner()
planner.add_task("Finish project", datetime.date(2023, 10, 15))
planner.add_task("Buy groceries", datetime.date(2023, 10, 10))
planner.show_tasks()
planner.complete_task("Buy groceries")
planner.show_tasks()
planner.remove_task("Finish project")
planner.show_tasks()
