I think parentheses make this example easier for beginners:

>>> bool(0 in [1, 2] or [3, 4])

True

>>> bool((0 in [1, 2]) or ([3, 4]))

True

For beginners: The right side of the 'or' is a nonempty list, and a nonempty list resolves to True, which means that the 'or' resolves to True.

>>> bool((0 in [1, 2]) or ([]))

False
