Peak programming

print("odd" if num % 2 else "even")That's the native python version, for those curious
That's way too non-convoluted enough

I love
something = condition and result1 or result2in luawrote on last edited by [email protected]Python does that, too.

Python is kinda like that in general, unless you try to make it read like ass

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 % 2isn'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.

Clearly an inferior language. /s

In JS 0 is the same as False

All of those languages will convert numbers into booleans, 0 is false, all other numbers are true.

The joys of dynamic typing.

Ah, that makes sense.

0 is false in C, Python, and JS. It should work

You'd be surprised.
But seriously, numbers can be used as booleans in an impressive number of languages. Including machine code for almost every machine out there.

Why is the return first?

That makes sense. However,
num % 2equaling 0 would mean it's even, and not "odd" like the ternary operator is outputting, yeah? -

In JS at least, there's a concept of truthiness and falsiness.
0,undefined,null, and a few other non-boolean values are treated asfalseif used in conditionals and logical operations, while every other value is treated astrue. I'm pretty sure python has something similar. -

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 -

The ternary syntax is really my only real gripe with python design -- putting the conditional BETWEEN the true and false values feels so very messy to me.

wrote on last edited by [email protected]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.
