本文实例为大家分享了python+logging+yaml实现日志分割的具体代码，供大家参考，具体内容如下

1、建立log.yaml文件

version: 1

disable_existing_loggers: False

formatters:

simple:

format: "%(asctime)s - %(filename)s - %(levelname)s - %(message)s"

datefmt: '%F %T'

handlers:

console:

class: logging.StreamHandler

level: DEBUG

formatter: simple

stream: ext://sys.stdout

info_file_handler:

class: logging.handlers.TimedRotatingFileHandler

level: DEBUG

formatter: simple

filename: ./mylog/log.log #这个路径根据自己的日志存放路径填写

interval: 1

backupCount: 2 #most 2 extensions

encoding: utf8

when: H #这里是按小时生成

root:

level: INFO

handlers: [console, info_file_handler]

2、在自己的app.py中引用log.yaml


import yaml
import logging.config
import os
def setup_logging(default_path='log.yaml', default_level=logging.INFO):
 """
 Setup logging configuration
 """
 if os.path.exists("mylog"):
  pass
 else:
  os.mkdir('mylog')
 path = default_path
 if os.path.exists(path):
  with open(path, 'rt') as f:
   config = yaml.load(f.read())
  logging.config.dictConfig(config)
 else:
  logging.basicConfig(level=default_level)
  print('the input path doesn\'t exist')
setup_logging(default_path='./log.yaml')
logger = logging.getLogger()
