input: Write a function to generate a random number between two given numbers.
  def random_number_generator(min, max):
      return random.randint(min, max)
  assert random_number_generator(2, 5) in [2, 3, 4, 5]
  assert random_number_generator(1, 10) in [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
output: def random_number_generator(min, max):
      return random.randint(min, max)
