How can I use pickle to save a dict?
...on 2, using the default protocol (0) is not only incredibly inefficient on time and space, but it can't actually handle many things that protocol 2+ handles just fine (e.g. new-style classes that use __slots__). I'm not saying you should always use HIGHEST_PROTOCOL, but ensuring you don't use protoc...
