Your first example is all one statement. Within that statement you are defining elements of a list. Unfortunately you are defining some of those elements in terms of others, but they don't exist until the statement has completed. If you break the statement up into an initial list formation statement followed by additional statements that successively append to the list, you will be able to refer to "previously-defined" list elements on the right side of assignments.
