If we need to read several configurations, each one having more priority than the previous one, we can use the same :class:`ConfigParser` instance to override previous defined data and keep not redefined data.

.. doctest::

>>> config = configparser.ConfigParser()
>>> config.read('example.ini')
['example.ini']
>>> config['topsecret.server.com']['Port']
'50022'
>>> config.read_string("[topsecret.server.com]\nPort=48484")
>>> config['topsecret.server.com']['Port']
'48484'
>>> config.read_dict({"topsecret.server.com": {"Port": 21212}})
>>> config['topsecret.server.com']['Port']
'21212'
>>> config['topsecret.server.com']['ForwardX11']
'no'

This behaviour is equivalent to a :meth:`ConfigParser.read` call with several files passed to ``filenames`` parameter.
