#带参数修饰器函数被调用时必须返回一个新的修饰器函数
def decoratorArgs(x,y):
def decorator(f):
def func(*args,**keywordArgs):
print 'invoke: %s(%s,%s)' % (f.__name__,x,y)
result=f(*args,**keywordArgs)
print 'invoked: %s(%s,%s)' % (f.__name__,x,y)
return result

@decoratorArgs(1,2)
def hello(arg):
print 'hello:',arg

print输出:
invoke: hello(1,2) hello: abc invoked: hello(1,2)
