Antoine Pitrou <pit...@free.fr> added the comment: I would rather document it in TextIOBase: http://docs.python.org/dev/library/io.html#io.TextIOBase
With text I/O streams, tell() returns an arbitrary "position cookie", meaning you can't meaningfully do arithmetic on it: this is why cur-relative seeking and end-relative seeking isn't supported. Of course, on StringIO the "arbitrary position cookie" is a perfectly well-defined character offset, so we *could* specifically enhance StringIO.tell. Whether it's a good idea to do it (while arbitrary text files would still have the limitation) is left to debate. ---------- assignee: -> docs@python components: +Documentation nosy: +docs@python, pitrou type: enhancement -> behavior versions: +Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12922> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
