I'm new to Python but not as a developer. Here, I'm using a library to create an aws `cloudformation` stack. I want to replace the `eks_cluster_name` for the `ClusterName`. Apparently, I can't because the data types are different.

<@Marc> that'll happen on your last iteration because `s[ind]` will be grabbing your last value, so `s[ind + 1]` will be out of range. You need to check for that before trying to access `s[ind + 1]`

Yes, if there's X elements in `s`, ie the length of `s`, then on the last iteration of your loop, `ind` will be equal to X, and `ind + 1` will be &gt; X
