no, it's not -- sorted() is a function, not a method. and there is a reason it's not list.sorted() (more than one actually)
It turns out the OP wan't asking for exactly what I thought, but the point still stands: mutating methods return None. That is a consistent interface standard in Python.
But your suggestion of an .appended() method does tie in to the "fluid interface" conversation on this list a while back -- if you are interested in the idea, I suggest you search the archives.

Yes, I know the difference between a function and method and understand the motivation for the function 'sorted' versus a method. The idea was that there was a strong enough need in the past to include another 'tense' of sort that returned a transformed list from the input iterable. I presume that list.appended could do an analogous thing. I do, however, appreciate the pointer to the 'fluid interface' conversation.
