Review Python Lists (Exercises)
00:00
And let’s sneak in a bit more practice before you finish up with the course. Create a tuple called data with two values. The first value should be the tuple (1, 2), and the second value should be the tuple (3, 4).
00:13
Then write a for loop that loops over data and prints the sum of each nested tuple. The outputs should look like shown below. So it should say Row 1 sum: 3, and then Row 2 sum: 7.
00:30
There’s a bit more. Create the list that contains the integers [4, 3, 2, 1], and then assign it to the variable numbers. Then create a copy of the numbers list using the slice notation with [:].
00:45
And finally, sort the numbers list in numerical order using the .sort() method. So just a couple more review exercises to strengthen your learning.

Hello Martin,
I have same question as Ivan**

Hi @Ivan Mladenovity and @Syed, you can use enumerate(), but you don’t have to.
You can check out some possible solutions in the related lesson on Tuple Sums in the Tuples and Lists Exercises Course.

data = [(1, 2), (3, 4)]
for tup in data:
sum(tup)
print(f"Row {data.index(tup) + 1} sum: {sum(tup)}")

Thanks Ivan.

@ivan.dimitri Thank you for the demonstration! I believe line 3 of your code sum(tup) is not needed, since you can use that directly inside the f-string. Or you can assign it as a local variable, and call the variable in the f-string.

Hello Martin! Are we using enumerate here in for loop for Row 1 and Row 2?
