Python L.sort 與sorted

• L.sort()

  Definition : sort(key=None, reverse=False)
  Type : Function of None module
  L.sort(key=None, reverse=False) -> None -- stable sort IN PLACE
             

• sorted()

  Definition : sorted(iterable, *, key=None, reverse=False)
  Type : Function of builtins module
  Return a NEW sorted list from the items in iterable.
  
  *key* specifies a function of one argument that is used to extract a comparison key from each list element: key=str.lower. The default value is None (compare the elements directly).
  *reverse* is a boolean value. If set to True, then the list elements are sorted as if each comparison were reversed.
  
  L.sort()是對L進行就地排序，隻适用于清單。
  sorted()會建立清單，适用于可疊代對象。
