input: Write a python function to shuffle a list using the random.shuffle method.
  assert sorted(shuffle([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])) == [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
  assert sorted(shuffle([10, 20, 30, 40, 50])) == [10, 20, 30, 40, 50]
  assert sorted(shuffle([5, 7, 9, 8, 6, 4, 3])) == [3, 4, 5, 6, 7, 8, 9]
output: import random
  
  def shuffle(lst):
      random.shuffle(lst)
      return lst
