class VisitorHandler:
    def __init__(self):
        self.data = []
    
    def process(self, input_data):

result = handler.process(data)
print(f"Result: {result}")

visitor in Real World Scenario

# Real world visitor example
def process_visitor(data):
    """Process data using visitor"""
    try:
        result = transform_data(data)

class VisitorManager:
    """Manager class for visitor operations"""
    
    def __init__(self, config=None):
        self.config = config or {}
        self._initialized = False
    
    def initialize(self):
        """Initialize the visitor manager"""
