Newbie question about import

[Luca]

Hi all. I'm trying to do something with python import but isn't working for me.

Using python 2,5 I've a program structured like this:

* a main module called (for example) "mommy" with an __init__.py and a
file called "mommy.py"
* a __version__ var defined inside the main __init__.py

>From the mommy.py file I need to import the __version__ var, but I'm
really not able to do this! I fear this is a very stupid task to do...
my problem is that the file is called like the module.

Anyone can point me to the solution?
