etr2460 edited a comment on issue #9311: [cache warm_up] warm_up slice with dashboard default_filters URL: https://github.com/apache/incubator-superset/pull/9311#issuecomment-600318023 The main difference here applies if it's possible for a key to be set to a falsey value. If you have the dict: ```python d = { "key": None, "foo": False, } ``` then: ```python d.get("key", []) # equals None d.get("foo", {}) # equals False d.get("key") or [] # equals [] d.get("foo") or {} # equals {} ``` This is really important to get right if you try to iterate through an array after "getting" it like this, as iterating over False or None will throw
