python ImportError No module named

Question

I am very new at Python and I am getting this error:

Traceback (most recent call last):

  File "mountain.py", line 28, in ?

    from toolkit.interface import interface

ImportError: No module named toolkit.interface

Python is installed in a local directory:

My directory tree is like this:

(local directory)/site-packages/toolkit/interface.py

My code is in here

(local directory)/site-packages/toolkit/examples/mountain.py

To run the example I do

python mountain.py

, and in the code I have:

from toolkit.interface import interface

And i get the error that I wrote, I have already checked

sys.path

and there I have the directory

/site-packages

, also I have the file

__init__.py.bin

in the toolkit folder to indicate to Python that this is a package. I also have a

__init__.py.bin

in the examples directory.

I do not know why Python cannot find the file when it is in

sys.path

, any ideas? Can be a permissions problem? Do I need execution permission?

Based on your comments to orip's post, I guess this is what happened:

You edited __init__.py on windows.
The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file).
You used WinSCP to copy the file to your unix box.
WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data."
The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package.
You create __init__.py in the appropriate directory and everything works... ?
