input: Write a function to shuffle a given list of numbers. The function should use Python's `random` module to shuffle the list in place and then 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 len(shuffle_list([1, 2, 3, 4, 5])) == 5
output: 
  def shuffle_list(nums):
   random.shuffle(nums)
   return nums
