I took your "starter" code, and formatted it to be what I hope is an
acceptable program, Gobal_Config.py. See attached. I'm using Python
2.5.2. I put the two modules in the same folder with it, and executed
it in IDLE. I got this: ... File "C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\configobj.py", line 1637, in _parse ParseError, infile, cur_index) File "C:\Sandia_Meteors\New_Sentinel_Development\Sentuser_Utilities_Related\sentuser\configobj.py", line 1748, in _handle_error raise error ParseError: Invalid line at line "1". As far as I can tell, line 1 of config.obj looks OK. It's a comment. Something is amiss. Does PYTHONPATH apply in Win XP? I haven't played at the level of paths for a long time in any OS. We can worry about an install "package" later for the modules. It might be best for the users of this program. When I was using Python 2.4, I could find an entry on Start for it, and get an item on it under Python 2.4 called something like Library Paths. I don't see that at all on Python 2.5. Bad memory, I just checked on my laptop, which has 2.4; however, I recall being able to probe Python library paths. This may be irrelevant. The ConfigObj 4 Introduction and Ref doc doesn't seem to associate it with any version of Python. Its version is 4.5.3. Puzzled ... Marc Tompkins wrote:
