input: Write a function to calculate the dot product of two given lists. The function should take two lists as arguments and return the result of the dot product. If the length of the lists is not equal, the function should raise a ValueError.
  assert dot_product([1, 2], [3, 4])==11
  assert dot_product([1, 2, 3], [4, 5, 6])==32
  assert dot_product([], [])==0
  try:
      dot_product([1, 2], [3, 4, 5])
  except ValueError:
      print("Correctly raised ValueError")
  else:
      print("Failed to raise ValueError")
output: def dot_product(list1, list2):
      if len(list1) != len(list2):
          raise ValueError("The length of the lists is not equal")
      return sum(x * y for x, y in zip(list1, list2))
