# 普通的装饰器, 打印函数的运行时间
def decrator(func):
  def wrap(*args, **kwargs):
    start_time = time.time()
    res = func(*args, **kwargs)
    end_time = time.time()
    print('运行时间为', end_time-start_time)
    return res
  return wrap

def decrator(*dargs, **dkargs):
  def wrapper(func):
    def _wrapper(*args, **kargs):
      print ("装饰器参数:", dargs, dkargs)
      print ("函数参数:", args, kargs)
      return func(*args, **kargs)
    return _wrapper
  return wrapper

    def decorator(f):
