- When using rawContainer in the map task, Input will become string representation of a list, so we have to convert it to a list.
- Users also need to get the array index first to process specific element in the list.

what is eval(a)? is this a [] literal? could we get an example of it? is there any other way of getting the list object like loading it through json.loads or something?

yeah maybe we don't use eval in our examples... or at least json.loads
