Description:
 def import_locations(self, baken_file):
 """Import baken data files. ``import_locations()`` returns a dictionary with keys containing the section title, and values consisting of a collection :class:`Baken` objects. It expects data files in the format used by the baken_ amateur radio package, which is Windows INI style files such as: .. code-block:: ini [Abeche, Chad] latitude=14.460000 longitude=20.680000 height=0.000000 [GB3BUX] frequency=50.000 locator=IO93BF power=25 TX antenna=2 x Turnstile height=460 mode=A1A The reader uses the :mod:`configparser` module, so should be reasonably robust against encodings and such. The above file processed by ``import_locations()`` will return the following ``dict`` object:: {"Abeche, Chad": Baken(14.460, 20.680, None, None, None, 0.000, None, None, None, None, None), "GB3BUX": : Baken(None, None, "2 x Turnstile", None, 50.000, 460.000, "IO93BF", "A1A", None, 25, None)} Args:: baken_file (iter):
