python中自带的三个装饰器的实现

class A():


  @property
  def pfunc(self):
    return self.value

  @pfunc.setter
  def pfunc(self,value):
    self.value = value

  @property
  def pfunc1(self):
    print('this is property')

if __name__=="__main__":

  A.pfunc = 9
  print A.pfunc
  A.pfunc1

class A():
  def func(self,x,y):
    return x * y

  @classmethod
  def cfunc(cls,x,y):
    return x * y

if __name__=="__main__":
  print A().func(5,5)
  print A.cfunc(4,5)

class A():
  def func(self,x,y):
    return x * y

  @staticmethod
  def sfunc(x,y):
    return x * y

if __name__=="__main__":

  print A.sfunc(6,5)
