ロガーっていいなぁ

こんな書き方もできるし、

import logging


class LoggerBase(logging.Logger):
    _instance = None

    def __new__(cls) -> logging.Logger:
        if cls._instance is None:
            logging.basicConfig(
                format="%(asctime)s\t%(levelname)s\t%(message)s",
                level=logging.INFO,
            )
            cls._instance = logging.getLogger(__name__)
            return cls._instance


class Logger(LoggerBase):
    _logger = LoggerBase()

    @classmethod
    def info(cls, message: str):
        return cls._logger.info(msg=message)

    @classmethod
    def warning(cls, message: str):
        return cls._logger.warning(msg=message)

    @classmethod
    def error(cls, message: str):
        return cls._logger.error(msg=message, exc_info=True)


if __name__ == "__main__":
    Logger.info("テスト")

こっちのほうがスッキリしている気がする。

import logging


class Logger:
    _logger = None

    @classmethod
    def set_logger(cls, name: str):
        logging.basicConfig(
            format="%(name)s\t%(asctime)s\t%(levelname)s\t%(message)s",
            level=logging.INFO,
        )
        cls._logger = logging.getLogger(name)
        return cls._logger

    @classmethod
    def info(cls, msg: str):
        return cls._logger.info(msg=msg)

    @classmethod
    def warning(cls, msg: str):
        return cls._logger.warning(msg=msg)

    @classmethod
    def error(cls, msg: str):
        return cls._logger.error(msg=msg, exc_info=True)


if __name__ == "__main__":
    Logger.set_logger("pythonic")
    Logger.info("テステス")
