Python package setup with data files

I have a .mat file in my package that I want to be including when I build the package. I do this with

data_files=[('utide', ['utide/ut_constants.mat'])],

This builds just fine. The question I then have is, when I try to load in the mat file with scipy IO, I have no idea where this file is located, and how I should code it in to be proper. Do I just find the files buildpath and hard code it in? Or is there some more pythonic way to do this?

For anyone interested, the code can be found here.

Since ut_constants.mat will be in the utide package directory, you could specify its path like this:

import utide
import os

matfile = os.path.join(os.path.dirname(os.path.abspath(utide.__file__)),
                       'ut_constants.mat')

If you wish to define matfile in __init__.py, then you can find out where utide has been installed by looking at the special variable __file__:

matfile = os.path.join(os.path.dirname(os.path.abspath(__file__)),
                       'ut_constants.mat')
