  5     encoding gives the name of the encoding that the stream will be
  6     decoded or encoded with. It defaults to locale.getpreferredencoding(False).
  7     
  8     errors determines the strictness of encoding and decoding (see
  9     help(codecs.Codec) or the documentation for codecs.register) and
 10     defaults to "strict".
 11     
 12     newline controls how line endings are handled. It can be None, ‘‘,
 13     ‘\n‘, ‘\r‘, and ‘\r\n‘.  It works as follows:
 14     
 15     * On input, if newline is None, universal newlines mode is
 16       enabled. Lines in the input can end in ‘\n‘, ‘\r‘, or ‘\r\n‘, and
 17       these are translated into ‘\n‘ before being returned to the
 18       caller. If it is ‘‘, universal newline mode is enabled, but line
 19       endings are returned to the caller untranslated. If it has any of
 20       the other legal values, input lines are only terminated by the given
 21       string, and the line ending is returned to the caller untranslated.
 22     
 23     * On output, if newline is None, any ‘\n‘ characters written are
 24       translated to the system default line separator, os.linesep. If
 25       newline is ‘‘ or ‘\n‘, no translation takes place. If newline is any
 26       of the other legal values, any ‘\n‘ characters written are translated
 27       to the given string.
 28     
 29     If line_buffering is True, a call to flush is implied when a call to
 30     write contains a newline character.
