input: Write a function to shuffle a given list using Python's random module. If the input list is empty, return the same empty list.
  assert shuffle_list([1, 2, 3, 4, 5]) != [1, 2, 3, 4, 5]
  assert shuffle_list(['apple', 'banana', 'cherry']) != ['apple', 'banana', 'cherry']
  assert shuffle_list([]) == []
output: import random
  
  def shuffle_list(lst):
      if not lst:
          return lst
      shuffled = lst[:]
      random.shuffle(shuffled)
      return shuffled
