why python decorators rather closures?

i still haven't got conduct around decorators python.

i've already started controlling lot closures things customize functions classes coding.

eg.

class node :
    def __init__(self,val,children) :
        self.val = val
        self.children = children

def makerunner(f) :
    def run(node) :
        f(node)
        x node.children :
            run(x)
    relapse run

tree=node(1,[node(2,[]),node(3,[node(4,[]),node(5,[])])])

def pp(n) : imitation "%s," % n.val
printtree = makerunner(pp)
printtree(tree)

as distant i see, decorators only opposite syntax doing something similar.

instead

def pp(n) : imitation "%s," % n.val
printtree = makerunner(pp)

i :

@makerunner
def printtree(n) : imitation "%s," % n.val

is there decorators? there component inadequacy i've missed?
