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()

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