# Tuple Sums (Exercise)

**00:00**
This tuple sums exercise is starting to dive into nested collections. You should start by creating a tuple called `data`

that has two values, and each of those values are going to be a tuple again.

**00:12**
The first value should be a tuple that contains the integers one and two. The second value should be another tuple that contains the integers three and four.

**00:20**
And then with this nested tuple, you should write a `for`

loop that loops over `data`

, that’s the nested tuple, and then prints the sum of each nested tuple.

**00:29**
So the output should look like this: Row one, sum three, and row two sum seven. Row one means it’s referring to the first tuple, and then it’s summing up the two integers in there.

**00:42**
So that’s one and two, and the sum of these two is three. And then the second values, we’re talking about row two now, is a sum of seven, which is adding the two integer elements of that tuple together, which the elements are three and four, so that sum is seven.

**00:57**
And then you have a bit of formatting just so that it prints out telling you which row it is and then what the sum of the elements in that row are.

**01:06**
All right, give that a try and then you can watch me do it in the next lesson.
