如何将python luigi终端输出保存到日志文件中，并在日志文件名中加上时间戳

import logging

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')

logger = logging.getLogger(__name__)
log_file = 'log_{}.txt'.format(datetime.now().strftime('%Y%m%d%H%M%S'))

file_handler = logging.FileHandler(log_file)
logger.addHandler(file_handler)

logger.info('This is a log message.')

import logging
from datetime import datetime

logging.basicConfig(level=logging.INFO, format='%(asctime)s - %(levelname)s - %(message)s')

logger = logging.getLogger(__name__)
log_file = 'log_{}.txt'.format(datetime.now().strftime('%Y%m%d%H%M%S'))

file_handler = logging.FileHandler(log_file)
logger.addHandler(file_handler)

logger.info('This is a log message.')
