Boolean expression ( 0 or None and False)

Question

Question: 0 or None and False
why it give me None as answer? I totally don't understand
I thought None and False should be False because none of them are True, but my python shell tell me it's None. Why's that?

Example:
None and False
>>> None

False and None
>>> False

0 or None
>>> None

None or 0
>>> 0

It has to do with the behavior of 'and', which checks the first argument before the second (called short-circuit evaluation).
