Only if the original object is itself mutable, otherwise the memoryview is read-only. I would propose the following algorithm: 1) try to calculate the original object's hash; if it fails, consider the memoryview unhashable (the buffer is probably mutable) 2) otherwise, calculate the memoryview's hash with the same algorithm as bytes objects (so that it's compatible with equality comparisons) Regards Antoine. _______________________________________________ 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
