It defaults to locale.getpreferredencoding(False).errors determines the strictness of encoding and decoding (seehelp(codecs.Codec) or the documentation for codecs.register) anddefaults to "strict".newline controls how line endings are handled. It can be None, '','\n', '\r', and '\r\n'.  It works as follows:* On input, if newline is None, universal newlines mode isenabled. Lines in the input can end in '\n', '\r', or '\r\n', andthese are translated into '\n' before being returned to thecaller. If it is '', universal newline mode is enabled, but lineendings are returned to the caller untranslated. If it has any ofthe other legal values, input lines are only terminated by the givenstring, and the line ending is returned to the caller untranslated.* On output, if newline is None, any '\n' characters written aretranslated to the system default line separator, os.linesep. Ifnewline is '' or '\n', no translation takes place. If newline is anyof the other legal values, any '\n' characters written are translatedto the given string.If line_buffering is True, a call to flush is implied when a call towrite contains a newline character."""def close(self, *args, **kwargs): # real signature unknown
