Interesting. I wonder if other implementations like Jython and PyPy really adhere to this official guarantee. At least Jython has the same paragraph in its documentation and I would expect that PyPy follows it as well. http://www.jython.org/docs/library/stdtypes.html#mapping-types-dict Maybe this guarantee is just easy enough to build on the given implementation details of a platform that it's a common property. Iteration over data structures should tend to be deterministic, after all. Stefan -- http://mail.python.org/mailman/listinfo/python-list
