### logging

-　logging.debug

-　logging.info

-　logging.warning

-　logging.error

-　logging.critical

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

import   logging

logging.basicConfig(level=logging.DEBUG)

logging.debug("this is a debug")
logging.info("this is info")
logging.warning("this is warning")
logging.error("this is error")
logging.critical("this is critical")

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

### 装饰器
- 使用装饰器，打印函数执行的时间

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

import logging

LOG_FORMART = "%(asctime)s - %(levelname)s - %(message)s"
logging.basicConfig(format = LOG_FORMART)

def log(func):
    def wrapper(*arg, **kw):
        logging.error("this is info message")
        return func(*arg, **kw)
    return wrapper

@log
def test():
    print("test done")
   
test()

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

#####   使用装饰器，根据不同的函数，传入的日志不相同

LOG_FORMART = "%(asctime)s - %(levelname)s - %(message)s"
logging.basicConfig(format = LOG_FORMART, filename = "my.log")

def log(text):
    def decorator(func):
        def wrapper(*arg, **kw):
            logging.error(text)
            return func(*arg, **kw)
        return wrapper
    return decorator

@log("test done")
def test():
    print("test done")
   
@log("main log")
def main():
    print("main done")

test()
main()
