sorted
def sorted(__iterable: Iterable [_T],
              *,
              key: Optional[(_T) -> Any] =...,
              reverse: bool =...) -> List [_T]
--------------------
Return a new list containing all items from the iterable in ascending order. A custom key function can be supplied to customize the sort order, and the reverse flag can be set to request the result in descending order.
