Yo uso este codigo que tome de Click, que de hecho sería bueno que sea
parte de anyconfig.

def _posixify(name):
    return '-'.join(name.split()).lower()

def get_app_dir(app_name, roaming=True, force_posix=False):
    r"""Returns the config folder for the application.  The default behavior
    is to return whatever is most appropriate for the operating system.

    To give you an idea, for an app called ``"Foo Bar"``, something like
    the following folders could be returned:

    Mac OS X:
      ``~/Library/Application Support/Foo Bar``
    Mac OS X (POSIX):
      ``~/.foo-bar``
    Unix:
      ``~/.config/foo-bar``
    Unix (POSIX):
      ``~/.foo-bar``
    Win XP (roaming):
      ``C:\Documents and Settings\<user>\Local Settings\Application
Data\Foo Bar``
    Win XP (not roaming):
      ``C:\Documents and Settings\<user>\Application Data\Foo Bar``
    Win 7 (roaming):
      ``C:\Users\<user>\AppData\Roaming\Foo Bar``
    Win 7 (not roaming):
      ``C:\Users\<user>\AppData\Local\Foo Bar``

    .. versionadded:: 2.0

    :param app_name: the application name.  This should be properly capitalized
                     and can contain whitespace.
    :param roaming: controls if the folder should be roaming or not on Windows.
                    Has no affect otherwise.
    :param force_posix: if this is set to `True` then on any POSIX system the
                        folder will be stored in the home folder with a leading
                        dot instead of the XDG config home or darwin's
                        application support folder.
    """
    if sys.platform.startswith('win'):
        key = roaming and 'APPDATA' or 'LOCALAPPDATA'
        folder = os.environ.get(key)
        if folder is None:
            folder = os.path.expanduser('~')
        return os.path.join(folder, app_name)
    if force_posix:
        return os.path.join(os.path.expanduser('~/.' + _posixify(app_name)))
    if sys.platform == 'darwin':
        return os.path.join(os.path.expanduser(
            '~/Library/Application Support'), app_name)
    return os.path.join(
        os.environ.get('XDG_CONFIG_HOME', os.path.expanduser('~/.config')),
        _posixify(app_name))
