python怎么生成日志_如何创建一个日志文件来记录python中的每个步骤？

你知道，有一个^{}模块！在import logging

import os

logging.basicConfig(filename='tmp.log',

format='%(levelname)s %(asctime)s :: %(message)s',

level=logging.DEBUG)

# format is a formatter string, level shows what level of logs it will record

# in this case it is everything!

# Levels are as follows from most to least critical

# CRITICAL

# ERROR

# WARNING

# INFO

# DEBUG

do = True

yes = True

do_the_work = lambda: None

def main():

logging.debug("Inside of main()")

if do:

logging.debug("Inside of if do:")

do_the_work()

logging.debug("doing work")

if yes:

logging.debug("inside of if yes:")

do_the_work()

logging.debug("doing work")

for list in os.listdir('.'): # there were three files in my folder

logging.debug("inside of for each files/dirs calling list")

print('python')

logging.debug("calling sys.system python")

logging.debug("executing python with give dir path")

将产生以下输出：

^{pr2}$

您可以轻松地捕捉异常并让它们抛出更多关键事件。在try:

really_important_method()

except EndOfTheWorldError:

logging.critical("Duck and cover boys, it's gonna blow.")
