Terry J. Reedy <tjre...@udel.edu> added the comment: StringTranslatePseudoMapping (Mapping) is an awkward and not very descriptive name. It is similar to collections.defaultdict except that it uses a default value rather than a default factory. The latter is so defaults can be mutables. Would a subclass of similar to defaultdict be faster?
Unlike, defaultdict, the initialized default is used in get as well as __getitem__. This means that STPM.get ignores a passed-in default, contrary to the definition of Mapping.get. The method override is not needed. The internal self._get is only needed because it is called in both __getitem__ and get. Without the get override, it's body (with 'self.' added, can become the body of __getitem__. I suspect that this would make __getitem__ faster. Test this. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32880> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
