        I think the idea is it reads more naturally, so you can read it like this return A if statement is true else return B

          Is it really more natural for a non-programmer than “if statement is true than a else b”? I can’t evaluate because of decades of C, so for me the python logic is still bizarre.

            Maybe?

            For C at least it doesn’t have the actual words, so you need to know what the specific symbols are var = condition ? a : b. In that expression we don’t know what a or b are in regards to the condition.

            Python literally is a if condition else b, so it reads out what is being done.

        Edit… I reread your comment and realized that python does it differently and that everything I typed was irrelevant… I’m still gonna leave it if anyone is interested in ternary expressions, but I suppose the answer to your question is, that’s just how python does it.

        That’s how ternary operators are designed to work. In essence, if you’re looking to do a single line if/then, you can directly assign a variable from the result of a ternary expression.

        As an example, I was scripting something earlier where there may or may not be a value returned from a function, but I still had to do something with that return value later. For this thing, I was using JavaScript.

        I ended up with:

        return platform == "name"  ? "Option 1" : "Option 2"
        

        If I were to write that out in a typical if/then it would be:

        if (platform == "name") {
            return "option 1"
        } else {
            return "option 2"
        }
        
        

        A ternary starts with a boolean expression, then the if true value, else the false value. That’s returned to either a variable or if in a function like my example, to the object calling the function. It’s just a way to write less code that in many cases is easier to read.

    print( ["even", "odd"][num % 2] )

    If you need to avoid evaluating the wrong branch:

    print( [lambda: "even", lambda: "odd"][num % 2]() )

    Yeah… I played that “serial killer or programming language inventor” game.

    The only one I was completely in disagreement with was the inventor of Python. He’s definitely a mass-murderer

    num % 2 isn’t a boolean result in any of these languages, so I feel like it would always output “odd”

    Edit: 0 is false, everything else is true.
