Catalin Iacob added the comment: Could it be that Raymond's file had Unix line endings?
I tried to reproduce this, picked a file on my disk and indeed I got a negative number, but that file has Unix line endings. This is documented at http://docs.python.org/2/library/stdtypes.html#file.tell so probably there's nothing to do then. As for Armin's report in msg180145, even though it's not intuitive, this matches ftell's behavior on Windows, as documented in the Remarks section of http://msdn.microsoft.com/en-us/library/0ys3hc0b%28v=vs.100%29.aspx. The tell() method on fileobjects is explicitly documented as matching ftell behavior: "Return the file’s current position, like stdio‘s ftell()". So even though it's not intuitive at all, it's probably better to leave it as is. tell() returns the intuitive non zero position when opening with 'a' on Python3 and on Python 2.7 when using io.open so it's fixed for the future anyway. ---------- nosy: +catalin.iacob _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue16273> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
