input: Write a python function to find the intersection of two lists.
  assert get_intersection([1, 2, 3, 4], [3, 4, 5, 6]) == [3, 4]
  assert get_intersection([10, 20, 30], [5, 10, 15, 20]) == [10, 20]
  assert get_intersection(['a', 'b', 'c'], ['c', 'd', 'e']) == ['c']
output: def get_intersection(list1, list2):
      return list(set(list1) & set(list2))
