Python日志极简配置
配置
配置倾向
- 只输出到文件
- 按时间轮转,默认7d
- 日志格式:只记录必要的信息
import logging
from logging.handlers import TimedRotatingFileHandler
from os import path
def init_log_config(
filename: str,
*,
default_dir="/var/log",
logformat: str = ("[%(levelname)s %(asctime)s %(process)d_%(threadName)s %(filename)s:%(lineno)s:%(funcName)s] "
"%(message)s"),
loglevel: str = "warn",
backup_count: int = 7,
encoding="utf-8",
delay=True,
):
"""
:param filename: 文件名
:param default_dir:
:param logformat:
:param loglevel:
:param backup_count:
:param encoding:
:param delay:
:return:
"""
levelint = {
"debug": logging.DEBUG,
"info": logging.INFO,
"warn": logging.WARN,
"error": logging.ERROR
}[loglevel]
if not filename.startswith("/"):
filename = path.join(default_dir, filename)
logging.basicConfig(
format=logformat,
level=levelint,
handlers=[
TimedRotatingFileHandler(
filename,
when="d",
backupCount=backup_count,
encoding=encoding,
delay=delay,
)
]
)
使用方式
- 在程序最最最开始的地方开始初始化(我一般放在第一行)
init_log_config("log1.log", loglevel="debug")
import os, sys
- 业务中使用
logging.info("Start Do something")
