How to count how many times a value occurs in JSON?

Question

Python

With requests, I get data like this:

{'status': True, 'data': {'total': 111, 'helper': [{'id': 1, 'user': 'user1', 'helper': 'user2'}], 'all': {'total': 111, 'list': [{'id': 1, 'user': 'user3', 'helper': 'user4'} и т.д.

I need to count how many times 'helper': 'user2' occurs here (not counting the very first helper: 111, 'helper': [{'id': 1...) and add it to a variable, I tried many ways but my head is already boiling, please help
