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 certainly has its issues. I find that the things people have trouble with are the things I tend to like about it. Of course, reading it later is a problem sometimes. :)
Wait until you learn that postfix conditionals are syntactic sugar and the compiler* turns that line into the equivalent of $debugandprint(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 (and or) but it could be.
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.
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.
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.
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.
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("odd" if num % 2 else "even")That’s the native python version, for those curious

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.Oh, (you) (really) (like) (Lisp)? (That’s) (great!)
(is great (oh (really (like-p lisp you))))It’s kinda natural to me having used Perl a lot.
That’s not quite the argument you might think it is
Argument?
You know, the stuff in @_
heheh. I wasn’t really making an argument though
The joke was that Perl is a clusterfuck

Write only language!
I still reach for it sometimes.
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.
You do get the if in the middle of stuff though in the form print(debug message) if $debug

The ternary operator itself isn’t implemented in terms of
and(andor) but it could be.Luckily I don’t need to read or write bytecode and all that matters to me is the syntax
perl -e 'print "fart\n" if 1;'At least you guys have ternary syntax cries in kotlin.
It’s really special to not have ternary, but have Elvis.

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.

Clearly an inferior language. /s
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 BYep, it’s this

Maybe?

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.
Oh wow, I think I hate that… Condition between the results? Yuck.
