input: Write a python function to find the most frequent element in a list using the Counter class from the collections module.
  assert most_frequent_element([1, 3, 1, 4, 5, 3, 4, 3]) == 3
  assert most_frequent_element([7, 8, 9, 7, 7, 8]) == 7
  assert most_frequent_element([2, 2, 2, 1, 1]) == 2
output: def most_frequent_element(lst):
      from collections import Counter
      counter = Counter(lst)
      most_common_element, _ = counter.most_common(1)[0]
      return most_common_element
