# zip
|
|
|
|
Make a list that aggregates elements from each of the lists. Returns a list of lists, where the i-th list contains the i-th element from each of the argument lists. The `zip` function stops when the first input list is exhausted.

**Since:** 2.4

## Parameters
|
|
|
|
- `lts` : A list of lists.

|
|
zs = [2.5, 7.5, 12.4];
|
|
|
|
assert(zip([xs, ys, zs]) == [[10, 5, 2.5], [20, 15, 7.5], [30, 25, 12.4]]);
|

sum_up = function(elems) sum(elems);
