سؤال 57

In `a if condition else b`, which result expressions are evaluated?

Both `a` and `b` before the condition
Neither result expression; it returns the condition
Always `a`, because the `else` part is optional
Only `a` or `b`, whichever the condition selectsپاسخ درست

توضیح

Python tests the condition and evaluates only the result expression selected by that truth value. Evaluating both `a` and `b` first would destroy the construct's lazy branch behavior and could trigger effects from an unselected path.
