python学习之property进阶

#第一种方式：
# class Foo:
#  @property
#  def AAA(self):
#     print("get")
#
#  @AAA.setter
#  def AAA(self,value):
#     print('set',value)
#
#  @AAA.deleter
#  def AAA(self):
#     print('delete')

#第二种方式：
class Foo:
   def get_AAA(self):
      print('get')

   def set_AAA(self,value):
      print('set',value)

   def delete_AAA(self):
      print('delete')

   AAA=property(get_AAA,set_AAA,delete_AAA) #内置property三个参数与get,set,delete一一对应
#只有在属性AAA定义property后才能定义AAA.setter,AAA.deleter
f1=Foo()
f1.AAA
f1.AAA=12
