input: Write a python function to find the intersection of two lists.
  assert find_intersection([1, 2, 3, 4, 5], [3, 4, 5, 6, 7]) == [3, 4, 5]
  assert find_intersection([10, 20, 30, 40], [30, 40, 50, 60]) == [30, 40]
  assert find_intersection([7, 8, 9], [10, 11, 12]) == []
output: def find_intersection(list1, list2):
      return list(set(list1) & set(list2))
