示例
from logzero import logger
logger.debug("hello")
logger.info("info")
logger.warn("warn")
logger.error("error")
# This is how you'd log an exception
try:
raise Exception("this is a demo exception")
except Exception as e:
logger.exception(e)
添加日志滚动也很容易
import logzero
from logzero import logger
# Setup rotating logfile with 3 rotations, each with a maximum filesize of 1MB:
logzero.logfile("/tmp/rotating-logfile.log", maxBytes=1e6, backupCount=3)
# Log messages
logger.info("This log message goes to the console and the logfile")
下面是一些例子说明如何使用日志文件、自定义格式以及设置最低日志等级。
import logging
import logzero
from logzero import logger
# This log message goes to the console
logger.debug("hello")
# Set a minimum log level
logzero.loglevel(logging.INFO)
# Set a logfile (all future log messages are also saved there)
logzero.logfile("/tmp/logfile.log")
# You can also set a different loglevel for the file handler
logzero.logfile("/tmp/logfile.log", loglevel=logging.ERROR)
# Set a rotating logfile (replaces the previous logfile handler)
logzero.logfile("/tmp/rotating-logfile.log", maxBytes=1000000, backupCount=3)
# Disable logging to a file
logzero.logfile(None)
# Set a custom formatter
formatter = logging.Formatter('%(name)s - %(asctime)-15s - %(levelname)s: %(message)s');
logzero.formatter(formatter)
# Log some variables
logger.info("var1: %s, var2: %s", var1, var2评论
