How do I sort tuples by given element in Julia?

Question

If I have a list/array of tuples like this: [(15, 36, 39), (9, 40, 41)]

How do I sort these by the first element? By the last element? By their sum?

Answer 1

x=[(15, 36, 39), (9, 40, 41)]
sort(x, by=x->x[1])
sort(x, by=x->x[end])
sort(x, by=sum)

You could also write first / last instead of x->x[1] / x->x[end], depending on what you think looks nicer – Pseudohermaphrodite

Also as of 1.5, you can write x[begin] – Thyroiditis
