input: Write a python function to find the frequency of elements in a list using the Counter from the collections module.
  assert find_frequency([1, 2, 3, 4, 1, 2, 3]) == Counter({1: 2, 2: 2, 3: 2, 4: 1})
  assert find_frequency(['apple', 'banana', 'apple', 'orange', 'banana', 'banana']) == Counter({'banana': 3, 'apple': 2, 'orange': 1})
  assert find_frequency([5, 5, 5, 5, 5]) == Counter({5: 5})
output: from collections import Counter
  
  def find_frequency(lst):
      return Counter(lst)
