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: ['2315', 'g', 'E', '9447', '9549', 'N', 'S', '7331', 'x', 'e', 'l', '9679', '3307']
