[Python] logger実装

loggerの実装

logger.py

from logging import getLogger, StreamHandler, INFO, Formatter


def main():
    logger = get_logger()

    logger.info("logger実装")
    // [INFO]2023-06-08 22:35:49,969-logger実装(logger.py)


def get_logger():
    logger = getLogger("log")
    handler = StreamHandler()
    handler.setLevel(INFO)
    logger.setLevel(INFO)
    logger.addHandler(handler)

    formatter = Formatter('[%(levelname)s]%(asctime)s-%(message)s(%(filename)s)')
    handler.setFormatter(formatter)
    return logger


if __name__ == "__main__":
    main()

他のclassでも使用する場合

test.py

logger = getLogger("log")

logger.info("logger test")
// [INFO]2023-06-08 22:35:49,969-read args(test.py)
