input: Write a function to combine the elements of two lists into a list of tuples. The function should return a list of tuples where each tuple contains an element from each of the two input lists. If the given lists are empty, it should return an empty list.
  assert combine_list([1, 2, 3], [4, 5, 6])==[(1, 4), (2, 5), (3, 6)]
  assert combine_list([1, 2], [3, 4])==[(1, 3), (2, 4)]
  assert combine_list([], [])==[]
  assert combine_list([1], [2])==[(1, 2)]
output: def combine_list(list1, list2):
      return list(zip(list1, list2))
