For optimal performance, you should rewrite it in Rust:
inline_python::python! {
print(js2py.eval_js("(number) => number % 2 ? 'odd' : 'even'")(number))
};

And now you can use wasm to run it in a browser!
Full circle 😆
Make sure the browser is made using Rust and run on a VM running on Linux, compiled to WASM.
print("odd" if num % 2 else "even")
That's the native python version, for those curious
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.
Eh, reads pretty naturally to me. That said, (like I lisp)
Lisps makes more sense to me though
(if condition a b)
VS
a if condition else b
I was more talking about (+ a b) and such.

At least you guys have ternary syntax cries in kotlin.
It's really special to not have ternary, but have Elvis.

Oh wow, I think I hate that... Condition between the results? Yuck.
That's way too non-convoluted enough
Python is kinda like that in general, unless you try to make it read like ass
You would not believe the number of people I’ve interviewed who excel at making Python read like ass.
I mean, it does have enough ways to write the same thing that it can really allow for some funny code golf, but some people just have no sense of readability whatsoever.

Why is the return first?
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]() )
Cursed
Not as cursed as
print("eovdedn"[n%2::2])
Indeed
Please. That's C's ternary operator. JS is just a pile of garbage cosplaying as a programming language
Why do you say it's a pile of garbage?
Because of all the garbage
Clearly the garbage collector is too effective
No they're not supposed to be piling it up
Is a garbage collector not a garbage disposal. Smh.
One example that's giving you problems? Maybe even on a daily basis if you use it for work? What's garbage about it?
Just send pseudo code to AI and compile straight to binary.
Peak programming
I love something = condition and result1 or result2 in lua
Python does that, too.

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
Are you sure it isn't just that he's Dutch?
