I agree with the general concept of "Tools that enforce "expert level" coding standards do make code more concise, but also less comprehendible for the less experienced developers." but this does not seem applicable here - it's not "expert level" coding, the suggested method is obviously readable to anyone who writes Python and is something that a programmer who has never used Python would learn in their first day of learning Python, it's not an advanced concept. Probably the whole concept of idiomatic Python is that there shouldn't be different styles of Python to which you graduate according to skill or experience, but rather that the simple, readable way of writing things should be done by everyone, always, from novices to experts. Code-golfing with dense weirdness would be "anti-Pythonic" but this ternary expression would be readable even for if someone who's never seen Python would read it as pseudocode in some theoretical CS paper.
