          result = 10 / 2
          logger.debug("Calculation result: %s", result)
      except ZeroDivisionError as e:
          logger.error("An error occurred: %s", e)
      
      logger.warning("This is a warning message.")
      logger.critical("Important system critical message.")
      logger.info("User logged in.", user_id=12345)

  if __name__ == "__main__":
      logger.info("Starting the application.")
      main()
      logger.info("Application finished.")
