input: Write a python function to find the most frequent element in a list using the Counter class from the collections module.
  assert find_most_frequent([3, 4, 6, 3, 2, 8, 6, 7, 3]) == 3
  assert find_most_frequent([1, 2, 2, 3, 3, 3, 4]) == 3
  assert find_most_frequent([4, 4, 4, 4, 2, 2, 1]) == 4
  assert find_most_frequent([5, 5, 6, 6, 6, 5]) == 5
output: def find_most_frequent(lst):
      from collections import Counter
      count = Counter(lst)
      return count.most_common(1)[0][0]
