Code Examples

Basic dotenv Example

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

if __name__ == "__main__":
    main()

Advanced dotenv Usage

# Advanced dotenv usage
import sys

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

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

dotenv in Real World Scenario

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

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

dotenv Best Practice Example

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

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