input: Write a function to shuffle a list of numbers using Python's random module. The function should return the shuffled list.
  def shuffle_list(nums):
   import random
   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 isinstance(shuffle_list([1, 2, 3, 4, 5]), list)
output: def shuffle_list(nums):
   import random
   random.shuffle(nums)
   return nums
