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.
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 BIs 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?

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.
