I can see at least four ways to get the current size of the BytesIO buffer: py> obj = io.BytesIO(b"x"*12468) py> obj.getbuffer().nbytes 12468 py> len(obj.getvalue()) 12468 py> len(obj.getbuffer()) 12468 py> obj.seek(0, 2) 12468 As far as I can tell, BytesIO objects do not have a fixed size buffer. They will increase in size as needed, just like real file objects on a disk. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
