Teacher:In this task, you are given inputs i,j, and A, where i and j are integers and A is a list. You need to return the sum of all the numerical elements in the list A between the positions i and j (including positions i and j). Return 0 if no numerical element is present in the list between the given ranges. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.
Teacher: Now, understand the problem? Solve this instance: 7, 7, ['D', 'v', '673', 'v', 'f', '9191', '6197', '711', 'E', '9285', '9275', '9075', '9915', 'O', '6931', 'i', '253']
Student:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
