Code Examples

Basic decorator Example

# Basic decorator example in Python
def main():
    # Your decorator implementation here
    result = "decorator works!"
    print(result)
    return result

if __name__ == "__main__":
    main()

Advanced decorator Usage

# Advanced decorator usage
import sys

class DecoratorHandler:
    def __init__(self):
        self.data = []
    
    def process(self, input_data):
        """Process decorator data"""
        return processed_data

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

decorator in Real World Scenario

# Real world decorator example
def process_decorator(data):
    """Process data using decorator"""
    try:
        result = transform_data(data)
        return result
    except Exception as e:
        print(f"Error: {e}")
        return None

# Usage
data = get_input_data()
output = process_decorator(data)

decorator Best Practice Example

# Best practice for decorator
class DecoratorManager:
    """Manager class for decorator operations"""
    
    def __init__(self, config=None):
        self.config = config or {}
        self._initialized = False
    
    def initialize(self):
        """Initialize the decorator manager"""
        if not self._initialized:
            self._setup()
            self._initialized = True
    
    def _setup(self):
        """Internal setup method"""
        pass

# Usage
manager = DecoratorManager()
manager.initialize()
