[Tutor] What's up with Python 2.5.1's IDLE?

[Dick Moores]

Under Kent's tutelage, I've been experimenting with having no 
PYTHONDOC, and instead putting a .pth file in 
E:\Python25\lib\site-packages\ I named pointers.pth. The contents of 
pointers.pth is:
E:\Python25\
E:\PythonWork\
E:\PythonWork\Functions\
E:\Python25\lib\site-packages\
E:\Python25\lib\site-packages\mine

Here's what the Command Prompt shell shows for sys.path:
E:\Python25>python
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> from sys import path
 >>> for x in path:
...  print x
...

E:\Python25\lib\site-packages\setuptools-0.6c5-py2.5.egg
E:\Python25\lib\site-packages\dmath-0.9-py2.5.egg
C:\WINDOWS\system32\python25.zip
E:\Python25\DLLs
E:\Python25\lib
E:\Python25\lib\plat-win
E:\Python25\lib\lib-tk
E:\Python25
E:\Python25\lib\site-packages
E:\Python25\lib\site-packages\PIL
E:\PythonWork
E:\PythonWork\Functions
E:\Python25\lib\site-packages
E:\Python25\lib\site-packages\mine
E:\Python25\lib\site-packages\win32
E:\Python25\lib\site-packages\win32\lib
E:\Python25\lib\site-packages\Pythonwin
E:\Python25\lib\site-packages\wx-2.8-msw-unicode
 >>>
All good.

However, this is what IDLE's shell shows for sys.path:
 >>> from sys import path
 >>> for x in path:
	print x

	
E:\Python25\Lib\idlelib
E:\Python24\lib\site-packages\setuptools-0.6c5-py2.4.egg
C:\WINDOWS\system32\python24.zip
E:\Python25\Lib\idlelib
E:\Python24\DLLs
E:\Python24\lib
E:\Python24\lib\plat-win
E:\Python24\lib\lib-tk
E:\Python24
E:\Python24\lib\site-packages
E:\Python24\lib\site-packages\wx-2.6-msw-ansi

I do still have Python 2.4, but why does Python 2.5.1's IDLE's shell 
show all those things from 2.4, and only shows the path to itself in 2.5.1?

I like the editing ease of having a .pth file rather than a 
troublesome-to-edit PYTHONDOC, but I need to first clear up the 
problem with IDLE (which works fine with a PYTHONDOC).

Thanks,
