input: Write a function named create_dict that takes two lists as input and returns a dictionary where the elements from the first list are the keys and the elements from the second list are the corresponding values. If the two lists have different lengths, the function should return an empty dictionary.
  assert create_dict(['a', 'b', 'c'], [1, 2, 3])=={'a': 1, 'b': 2, 'c': 3}
  assert create_dict(['a', 'b'], [1, 2, 3])=={}
  assert create_dict(['a', 'b', 'c'], [1, 2])=={}
  assert create_dict([], [])=={}
output: def create_dict(keys, values):
      if len(keys) != len(values):
          return {}
      return dict(zip(keys, values))
