input: Write a function that takes two numbers as input, and generates a random number between them.
  
  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(10, 20) in range(10, 21)
  assert random_number_generator(-1, 1) in [-1, 0, 1]
  assert random_number_generator(0, 0) == 0
  assert random_number_generator(3, 3) == 3
output: def random_number_generator(min, max):
      return random.randint(min, max)
