Wow this has gotten awfully strange. I'm running Python on OS X. Here's a quick rundown of what I just found:
(a) If I open a terminal and then run my python script (./script.py), it fails giving me the RLock error I attached in my original e-mail. (b) If I open a FRESH terminal, run the interpreter (python), import threading & logging and then run the same exact code snipped in question (logging.basicConfig( ... )), it works fine (no errors). Further, running "threading.RLock" will generate the expected output. (specifically: <function RLock at 0x10e6870>). However... (c) Let's say I open a terminal and then run my script. It fails with, citing the RLock error. Then, in the *same* terminal window, I open the python interpreter, import logging and threading, and then run the same exact code snippet (logging.basicConfig( ... )). Despite the fact that I have imported all the required modules, I will get the same RLock error I received before. If I attempt to run the command "threading.RLock" in the interpreter, I receive the following error message: >>> threading.RLock Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no attribute 'RLock' ? ...now I'm even more confused. ;) Thoughts? .james On Sep 29, 2007, at 5:53 PM, Kent Johnson wrote: > James wrote: >> Here's the output of the requested commands: >> >>> import threading >> >>> threading.__file__ >> '/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/ >> threading.pyc' >>> >> Looks identical to the output you attached. > > Strange.
