In C implementation, write() calls underlaying flush() method when write_through=True. https://github.com/python/cpython/blob/3.6/Modules/_io/textio.c if (self->write_through) text_needflush = 1; if (self->line_buffering && (haslf || PyUnicode_FindChar(text, '\r', 0, PyUnicode_GET_LENGTH(text), 1) != -1)) needflush = 1; But pure Python implementation doesn't care write_through option at all. https://github.com/python/cpython/blob/3.6/Lib/_pyio.py self.buffer.write(b) if self._line_buffering and (haslf or "\r" in s): self.flush() When PyPy 3.5 is released, this difference may affects PyPy users. (I hadn't checked how PyPy provide io module.) |
