Code Examples

Basic itertools Example

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

if __name__ == "__main__":
    main()

Advanced itertools Usage

# Advanced itertools usage
import sys

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

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

itertools in Real World Scenario

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

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

itertools Best Practice Example

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

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