input: Write a function to sort a given list in descending order using Python. The function should take a list of integers as input and return the sorted list in descending order.
  assert sort_list_descending([3, 7, 5, 8,10]) == [10, 8, 7, 5, 3]
  assert sort_list_descending([1, 2, 3, 4, 5]) == [5, 4, 3, 2, 1]
  assert sort_list_descending([]) == []
  assert sort_list_descending([9, 8, 7, 6, 5]) == [9, 8, 7, 6, 5]
  assert sort_list_descending([1]) == [1]
output: return sorted(lst, reverse=True)
