input: Write a python function to create a dictionary from two lists, one for keys and one for values.
  assert createDict(['a', 'b', 'c'], [1, 2, 3]) == {'a': 1, 'b': 2, 'c': 3}
  assert createDict(['x', 'y', 'z'], [10, 20, 30]) == {'x': 10, 'y': 20, 'z': 30}
  assert createDict([], []) == {}
output: def createDict(keys, values):
      return dict(zip(keys, values))
