Re: [Python-Dev] Subtle difference between f-strings and str.format()

[Tim]

I have a hard time imaging how that could have come to be, but if it's true I'd say the unoptimized code was plain wrong. The dumbest possible way to implement `f() and g()` is also the correct ;-) way:

result = f() if not bool(result): result = g()

Heh - that's entirely wrong, isn't it? That's how `or` is implemented ;-) Same top-level point, though: result = f() if bool(result): result = g()
