Basic Python logging setup to print to console and output to file.

logging_setup.py

import logging

# Create a logger
logger = logging.getLogger('my_logger')
logger.setLevel(logging.DEBUG)

# Create handlers
console_handler = logging.StreamHandler()
console_handler.setLevel(logging.DEBUG)

file_handler = logging.FileHandler('logfile.log')
file_handler.setLevel(logging.DEBUG)

# Create formatters and add them to handlers
console_formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
console_handler.setFormatter(console_formatter)

file_formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_handler.setFormatter(file_formatter)

# Add handlers to the logger
logger.addHandler(console_handler)
logger.addHandler(file_handler)

# Example usage
logger.debug('This is a debug message')
logger.info('This is an info message')
logger.warning('This is a warning message')
logger.error('This is an error message')
logger.critical('This is a critical message')
