Yes. The 'file' documentation for readlines says documents that the argument is advisory and may be rounded up to an internal buffer size. io's readlines, on the other hand, says no more lines will be read if the total size of bytes read so far exceeds the hint. So, different semantics. > Apparently on 2.X sizehint does not have any effect as far as I can see. Have you played with large enough hints/small enough buffers? --David _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
