Code run from IDLE but not via double-clicking on its *.py

[n00m]

Oops.. not everything so super as I thought.
Incredible but from command line it results as:

D:\>python23\python d:\python23\00\socket6.py
Traceback (most recent call last):
  File "d:\python23\00\socket6.py", line 1, in ?
    import socket, thread
  File "D:\Python23\00\socket.py", line 3, in ?
    s1 = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
AttributeError: 'module' object has no attribute 'AF_INET'

D:\>

FROM IDLE 1.0.3 THE SAME SCRIPT WORKS PERFECTLY !!!

WHY ON THE EARTH <'module' object has no attribute 'AF_INET'> ???
