There was a problem hiding this comment.
From my POV it's better to validate mode value in __init__() in order to prevent the object instantiating with invalid data. in other words, validating mode value is a check of the invariant (mode field has supported value) and thus the object must not be created/instantiated if any of invariant checks failed.
