``'U'`` opens the file as a text file, but lines may be terminated by any of the
following: the Unix end-of-line convention ``'\n'``, the Macintosh convention
``'\r'``, or the Windows convention ``'\r\n'``. All of these external

without universal newlines support a *mode* with ``'U'`` is the same as normal
text mode. Note that file objects so opened also have an attribute called
:attr:`newlines` which has a value of ``None`` (if no newlines have yet been
seen), ``'\n'``, ``'\r'``, ``'\r\n'``, or a tuple containing all the newline
types seen.

``'w'`` or ``'a'``.

* The :mod:`fileinput` module was made more flexible. Unicode filenames are now
supported, and a *mode* parameter that defaults to ``"r"`` was added to the
:func:`input` function to allow opening files in binary or :term:`universal newlines`

:func:`open` to open the input files. Once you're iterating over the set of
