input: Write a function to shuffle a list of numbers using the `random.shuffle()` method. The function should return the shuffled list.
  
  import random
  
  def shuffle_list(nums):
      random.shuffle(nums)
      return nums
  
  assert shuffle_list([1, 2, 3, 4, 5])!=[1, 2, 3, 4, 5]
  assert shuffle_list([])==[]
  assert shuffle_list([1])==[1]
  assert shuffle_list([1, 2])!=[1, 2] or shuffle_list([1, 2])!=[2, 1]
output: import random
  
  def shuffle_list(nums):
      random.shuffle(nums)
      return nums
