Python v3日誌記錄

Question

我可以在Python 2中使用下面的代碼。我在Python 3上嘗試了它，並且出現錯誤。任何人都能解釋爲什麼

代碼：

import logging 
import logging.handlers 

LOG_FILENAME = 'poller.log' 

# Set up a specific logger with our desired output level 
poll_logger = logging.getLogger('pollerLog') 

# Add the log message handler to the logger 
log_rotator = logging.handlers.TimedRotatingFileHandler(LOG_FILENAME, when='d', interval=1, backupCount=5, encoding=None, delay=False, utc=False) 
poll_logger.addHandler(log_rotator) 

# Roll over on application start 
poll_logger.handlers[0].doRollover() 

錯誤：

Traceback (most recent call last): 
    File "logR.py", line 10, in <module> 
    log_rotator = logging.handlers.TimedRotatingFileHandler(LOG_FILENAME, when='d', interval=1, back 
upCount=5, encoding=None, delay=False, utc=False) 
    File "C:\LynxApps\Python31\lib\logging\handlers.py", line 206, in __init__ 
    t = os.stat(filename)[ST_MTIME] 
NameError: global name 'ST_MTIME' is not defined 

我檢查了下面的文件，我看不出有任何區別：

Python的V2 - >http://docs.python.org/library/logging.html#timedrotatingfilehandler

Python v3 - >http://docs.python.org/py3k/library/logging.handlers.html?highlight=logging#timedrotatingfilehandler

Answer 1

這是Python 3.1.3中的一個錯誤（請參閱issue on bugs.python.org）。

據說它已經在Python 3.2中修復了。
