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 alphabetical elements in the given list. Return 0 if no alphabetical element in the list

Let me give you an example: ['238', 'h', '92', 'U', '2799']
The answer to this example can be: 2
Here is why: Here, the alphabetical elements in the input list are 'h' and 'U', hence their count is 2.

OK. solve this:
['b', 'C', '8865', 'l', 'L', 'f', 'U', '2109', 'G', 'a', 'G', 'N', 'O', '1407', '6399', '4965', 'w', '2085', 'P', '4007', '1621', '225', 'y', '3105', 'I', '1973', '463', '7033', '999', 'h', 'J', '1593', '8501', 'R', '8273', 'N', '7641', '3189', 'S', 'N']
