input: Write a function that takes a list as input and shuffles its elements. The function should use Python's random module to shuffle the list in place. Return the shuffled list.
  
  def shuffle_list(list):
      random.seed()
      random.shuffle(list)
      return list
  
  assert shuffle_list([1, 2, 3, 4, 5]) != [1, 2, 3, 4, 5]
  assert len(shuffle_list([1, 2, 3, 4, 5])) == 5
  assert sorted(shuffle_list([1, 2, 3, 4, 5])) == [1, 2, 3, 4, 5]
output: def shuffle_list(list):
      random.seed()
      random.shuffle(list)
      return list
