A better message might be:
You tried to use l[10] when l is only 4 elements long. You can add
items to l using l.append(value), or check your index value to make
sure that's really the position you wanted to access.
It would make sense to me to upgrade this particular error message to
IndexError: list assignment index 10 out of range 0 to 3 if it can
be done without too much difficulty or overhead. (An empty list, and
perhaps one with only 1 element, would be special cases.) Come to think
of it, is the word "assignment" needed?
It would help if the line were "l1[10] = 2 * l2[13] + 3".
You're right of course; "assignment" IS meaningful; I missed it.
