python 日志 装饰器_Python---进阶---logging---装饰器打印日志

#### logging

- logging.debug

- logging.info

- logging.warning

- logging.error

- logging.critical

--------------------------------------

import logging

LOG_FORMART = "%(asctime)s - %(levelmane)s - %(message)s"

logging.basicConfig(level=logging.DEBUG, format=LOG_FORMART, filename="my.log")

logging.debug("this is  debug")

logging.info("this is  info")

logging.warning("this is  warning")

logging.error("this is  error")

logging.critical("this is  critical")

----------------------------------

二、装饰器

-　　使用装饰器，打印函数执行的时间

----------------------------------

#####  使用装饰器，根据不同的函数，传入的日志不相同

#def log(func):

#    def wrapper(*arg, **kv):

#        logging.error("this is info message")

#        return func(*arg, **kv)

#    return wrapper

def log(text):

def decorator(func):

def wrapper(*arg, **kv):

logging.error(text)

return func(*arg, **kv)

return wrapper

return decorator

@log("test donw")

def test():

print("test done")

@log("main done")

def main():

print("main done")

test()

main()
