Python sys.path internal?

Question

Recently, I copied a python project from different place and got below issue:

I installed python on D:\python27

then I checked sys.path using below code:

import sys
sys.path

I got below ouput:

...
'C:\\Python27\\Lib', 
'C:\\Python27\\DLLs',

I have no idea where python append the old trash python install path into sys.path. Share any idea will be appreciated. Thanks!

PS: I also checked the PYTHONPATH variable in registry table:

D:\Python27\Lib;D:\Python27\DLLs;D:\Python27\Lib\lib-tk

I would check a few things:

Verify that you do not have an older version of Python installed at c:\Python.
Make sure to test the value of sys.path before importing or running anything else.
If you still have the problem, try running Python directly from its installed path on your D: drive.

Good luck.

I had ever installed the older version in C:\python, but now it is not existing. Do you have any idea about how the python to build sys.path? – meng jue Jul 23 '13 at 04:07
It looks to me that your older Python was not properly uninstalled. – Who8MyLunch Jul 23 '13 at 12:13

The registry is consulted when setting up sys.path. Unset the registry keys and your python sys.path should look cleaner. For more about how sys.path works, see this answer https://stackoverflow.com/a/38403654/850326
