New submission from Sebastian Rittau <srit...@rittau.biz>: See https://github.com/python/typing/issues/518 for context.
The typing documentation for 3.6.4rc1 states: > typing.io ... defines the generic type IO[AnyStr] and aliases TextIO and > BinaryIO for respectively IO[str] and IO[bytes]. In the current implementation TextIO and BinaryIO are not aliases, but instead derived from IO. This means that values of type IO[...], and especially IO[Any] can not be assigned where TextIO or BinaryIO is expected. ---------- assignee: docs@python components: Documentation messages: 308083 nosy: docs@python, srittau priority: normal severity: normal status: open title: typing.TextIO and BinaryIO are not aliases of IO[...] versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32284> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
