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: ['M', '5591', '1983', '1971', '3803', '9971', '9389', '5221', '6015', '3117', 'm', 'H']
