That's not quite the argument you might think it is

print( ["even", "odd"][num % 2] )If you need to avoid evaluating the wrong branch:
print( [lambda: "even", lambda: "odd"][num % 2]() ) -

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

You know, the stuff in @_

Are you just referring to how Python uses the English
and/orinstead of the more common&&/||? I think what the user above you was talking about was Lua's strange ternary syntax usingand/or.wrote on last edited by [email protected]no, the linked table shows how python also returns the first non-falsey result of an
a or bexpression rather than just giving a boolean. it's useful for initialising optional reference args:def foo(a: list = None) a = a or []works with
andas well. -

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?
-
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.

It's kinda natural to me having used Perl a lot.
wrote on last edited by [email protected]You clearly haven't used Perl a lot. Perl's ternary looks like:
$even = $num % 2 ? "nay" : "yay";
Incidentally, it is also the same as PHP's, but mainly because PHP stole it.

(if condition a b)
VS
a if condition else b

Because of all the garbage

You do get the if in the middle of stuff though in the form print(debug message) if $debug

Make sure the browser is made using Rust and run on a VM running on Linux, compiled to WASM.

Just send pseudo code to AI and compile straight to binary.

Wait until you learn that postfix conditionals are syntactic sugar and the compiler* turns that line into the equivalent of
$debug and print(debug message), putting the conditional in first place, a lot like the ternary operator.* Perl compiles to bytecode before running.
The ternary operator itself isn't implemented in terms of
and(andor) but it could be. -

Clearly the garbage collector is too effective

I was more talking about
(+ a b)and such.
