Sass for loop error

I'm trying to use a for loop to append values to my list variable, ra. This is my code:

$ra: ();
@for $i from 1 through 10 {
    append($ra, $i, comma);
}

I'm getting this error:

Error: expected "{".
        append($ra, $i, comma);
  style.scss 3:24  root stylesheet

What are you trying to accomplish? The @for loop expects some kind of CSS output. It seems like you're just trying to programmatically store the values 1-10 in a variable.

Yes. I wanted to store different shadows in the list & after the loop set an element's box-shadow property to the list. I got the same error when I tried that, so I thought I should simplify the code until I get the loop working.

Gotcha! Can you link me to a snapshot (e.g. Workspace, Codepen, Sassmeister, etc) of your full code? I can try to help you work this out.

This blog post might be of help: https://hugogiraudel.com/2013/07/15/understanding-sass-lists/

After reading the article, I tried assigning the value returned by append() to $ra, & it worked! Thanks for your help :)
