Hi all,

No issues with the exercise, at all. But, I’m just curious at to why it says on the ‘insert’ example that inserting “dog” at index 1 moves everything down by 1. Surely, it moves everything UP by 1 (i.e. “bat” goes from index 1 to 2, and “cat” goes from index 2 to 3)? Or have I completely misunderstood what this means?

Cheers
Josh

the indices go up indeed, but the instructions do not refer to the indices.

a list is a queue of items, so lets say you are in queue for a theme park ride. The moment someone is placed in front of you, you moved further down the queue.

I’m curious about inserting the variable in this exercise. Why don’t .insert(animals.index(“duck”), “…”) instead of the variable?

@jjhiggins97, you will find that many of the scripts taught here (at least jn Python) employ intermediate variables for clarity.
