input: Write a function to combine the elements of two lists into a list of tuples. The function should return the combined list of tuples.
  assert combine_list([1, 2, 3], [4, 5, 6]) == [(1, 4), (2, 5), (3, 6)]
  assert combine_list(["a", "b"], [1, 2]) == [("a", 1), ("b", 2)]
  assert combine_list([1], ["a"]) == [(1, "a")]
  assert combine_list([], [1, 2]) == []
  assert combine_list([1, 2], []) == []
output: def combine_list(list1, list2):
      return list(zip(list1, list2))
