Returns a new instance of the :class:`FileHandler` class. The specified file is

(only usable if ``text=True`` or ``universal_newlines=True``)
- any other positive value means use a buffer of approximately that
size
.. versionchanged:: 3.3.1
*bufsize* now defaults to -1 to enable buffering by default to match the
