input: Write a python function to shuffle a list using the `random.sample` function.
  assert set(shuffle_list([1, 2, 3, 4, 5, 6]))=={1, 2, 3, 4, 5, 6}
  assert set(shuffle_list([10, 20, 30, 40, 50]))=={10, 20, 30, 40, 50}
  assert set(shuffle_list(['a', 'b', 'c', 'd', 'e']))=={'a', 'b', 'c', 'd', 'e'}
output: import random
  
  def shuffle_list(lst):
      return random.sample(lst, len(lst))
