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)
  
  It's kinda natural to me having used Perl a lot.
  
  I think it's just what you're used to. Imo it really matters that it's keywords and not operator symbols - it's meant to read closer to natural language. I prefer the c version when it's ? and :, but I like them this way round when it's if and else.
- That's way too non-convoluted enough
  
  Python is kinda like that in general, unless you try to make it read like ass
- Oh wow, I think I hate that... Condition between the results? Yuck.
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 😆
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
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])
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.
  
  https://docs.python.org/3/library/stdtypes.html#boolean-operations-and-or-not
  
  Are you just referring to how Python uses the English and/or instead of the more common &&/||? I think what the user above you was talking about was Lua's strange ternary syntax using and/or.
- often I do a function called elvis XD with the next signature elvis(condition, res1, res2)
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?
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.
- All of those languages will convert numbers into booleans, 0 is false, all other numbers are true.
  
  Ah that makes sense.
- In JS at least, there's a concept of truthiness and falsiness. 0, undefined, null, and a few other non-boolean values are treated as false if used in conditionals and logical operations, while every other value is treated as true. I'm pretty sure python has something similar.
  
  It does. Empty collections, 0, None
- The joys of dynamic typing.
- In JS 0 is the same as False
  
  They are not the same, but 0 can be implicitly converted to false.
  
  What do you get if you do: 0 === false
- 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.
