There's no contradiction; you're doing two entirely different things.If you want to compare a non-boolean to False or True, expect it'll always be false. They are different types. (except for the int historical nonsense I mentioned earlier).
If you want to duplicate what the second expression does, you'll have to convert the str to a boolean, using the bool() function.[1]
>>> bool("") == False
True
[1] Technically it's not a function but a "type" operation, or
something. But it quacks like a function, and I can't be bothered, at
least not for this discussion.
