input: Write a function to shuffle a list of numbers using the random.shuffle() function. 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]) == [2, 3, 1, 5, 4]
  assert shuffle_list([5, 4, 3, 2, 1]) == [3, 1, 4, 5, 2]
  assert shuffle_list([10, 20, 30, 40]) == [40, 10, 30, 20]
  assert shuffle_list([7, 8, 9, 0]) == [0, 8, 7, 9]
  assert shuffle_list([]) == []
output: def shuffle_list(nums):
      random.shuffle(nums)
      return nums
