Teacher: In this task, you are given an input list. A list contains several comma-separated items written within brackets. You need to return the count of all the numerical elements in the given list. Return 0 if no numerical element in the list.
Teacher: Now, understand the problem? If you are still confused, see the following example:
['238', 'h', '92', 'U', '2799']
Solution: 3
Reason: Here, the numbers in the input list are '238', '92' and '2799', hence their count is 3.

Now, solve this instance: ['1535', '2025', 'W', '3515', 'E', 'G', 'H', '4915', 'q', 'u', 'H', '5617', 'y']
