Thanks for all suggestions! I like this solution a lot.
I agree with your statement about mixed operators and explicit
parentheses -- expecially since the eye/brain parser often does it
wrong, and I believe you demonstrated that above...
In [29]: print(False and (False or True))
False
In [30]: print(False and False or True)
True

Yes, I much prefer the parentheses -- partly because PEP-8 suggests it
but mostly because the escapes get lost too easily.
