LOG_PATH = f'./{time.strftime("%Y-%m-%d_%H-%M-%S", time.localtime())}.log'
LOG = logging.getLogger(__name__)
formatter = logging.Formatter('[%(asctime)s][%(levelname)s][%(filename)s:%(lineno)d][%(threadName)s][%(funcName)s] %(message)s')
LOG.setLevel(logging.DEBUG)


def init_log():
    sh = logging.StreamHandler()
    sh.setFormatter(formatter)
    sh.setLevel(logging.DEBUG)
    fh = logging.FileHandler(LOG_PATH, 'w', encoding='utf-8')
    fh.setFormatter(formatter)
    fh.setLevel(logging.DEBUG)
    LOG.addHandler(sh)
    LOG.addHandler(fh)
