Welcome to the advanced logging framework guide! Whether you're debugging complex applications or monitoring system behavior, mastering logging is essential. Let's dive into key concepts and practical examples.

1. Core Concepts 💡

  • Log Levels: DEBUG, INFO, WARNING, ERROR, CRITICAL (use ⚠️ for warnings)
  • Handlers: Direct logs to console, files, or network (example: logging.FileHandler)
  • Formatters: Customize log message format (try %(asctime)s for timestamps)
import logging
logging.basicConfig(level=logging.DEBUG)
logger = logging.getLogger(__name__)
logger.debug("This is a debug message")

2. Advanced Configuration 🛠️

🔧 Customize logging with:

  • Multiple handlers (e.g., file + console)
  • Rotating log files via RotatingFileHandler
  • Custom log formats using Formatter
