One part you missed, sorted is actually closer to:

def sorted(iterable, cmp=None, key=None, reverse=False):
    "sorted(iterable, cmp=None, key=None, reverse=False) --> new sorted list"
    s=list(iterable)
    s.sort(cmp, key, reverse)
    return s

The point being that while in general only a list will have a sort 
method, the sorted builtin may be called on any iterable and will 
return a sorted list.

Also note that it only accepts specific named arguments, and has a 
docstring.
