If your use case allows the item to be removed, then use: key, val = myDict.popitem() Otherwise, use: key, val = next(iter(MyDict.items())) The latter is nice because next() allows you to supply a default argument in case the dictionary is emtpy: key, val = next(iter(MyDict.items()), (None, None)) Raymond --------- follow my tips and recipes on twitter: @raymondh -- http://mail.python.org/mailman/listinfo/python-list
