logzero打印日志
logzero是Python的一个日志库，易用性比logging更高一些，不同日志级别可显示不同颜色，很赞。
安装的话很简单，只需要pip install logzero即可。使用的话，先看最简单的，日志输出到控制台
from logzero import logger
# log messages are sent to the console
logger.debug("hello")
logger.info("info")
logger.warning("warning")
logger.error("error")
以上代码运行结果如下图所示
当然还可以设置日志级别，控制日志显示
import logging
import logzero
from logzero import logger
logzero.loglevel(logging.WARNING) # set log level
logger.debug("hello") # will not show up
logger.info("info") # will not show up
logger.warning("warning")
logger.error("error")
日志除打印到控制台外，还可以打到文件中
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)
