python 的logging 的配置，有这一篇就够了
参考 文章：https://www.cnblogs.com/nwpuxuezha/p/9038172.html
python 自带
import logging
#输出的日志文件目录
LOG_FILE_NAME = "logs/log.log"
# 得到 logger 对象
logger = logging.getLogger()
# 初始化 logger
def log_init():
# 输出的格式
formatter = logging.Formatter(
fmt='%(asctime)s %(filename)s [line:%(lineno)d] %(levelname)s :%(message)s',
datefmt='%Y-%m-%d %H:%M:%S')
#设置级别
logger.setLevel(logging.DEBUG)
#控制台的输出
ch = logging.StreamHandler()
ch.setFormatter(formatter)
# log文件的记录
fh = logging.FileHandler(LOG_FILE_NAME)
fh.setFormatter(formatter)
#将输出的流 添加给logger
logger.addHandler(ch)
logger.addHandler(fh)
def test():
logger.info("info")
logger.error("error")
if __name__ == "__main__":
log_init()
test()
