Lists get sublist

Block returns sublist (slice) of list variable.

First argument is variable containing list, second and third argument should be either Int or None. Default arguments are None and means skipped slicing option (i.e. setting pulldown to “first” or “last”).

In case slicing can’t be performed because slicing index is for example string then None is returned.
