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: ['e', '1581', '4939', '1073', 'o', 'a', 'S', '4657', '3567', '7909', '9949', '3107', '2611']
