A post was split to a new topic: Why do we use range here?

I tried to tweak the function and think of the explanation based on the printed result.
so far I found that if the function return x[0] it will return 6, x[1] return 10, and x[2] return 14.
But still couldn’t understand why returning x[i] would result in 14 (the last value of the list?)
I still can’t explain how the code works.

Recall that i above is in the index range of the list, meaning it will point to one or another element, depending which index it currently is. The last value for i is 2, and since the last value in the list was doubled, x[i] will be that new value, 14.
