用法一
class Test(object):
def __init__(self):
self.__Num = 100
def setNum(self,Num):
print("---set---")
self.__Num = Num
def getNum(self):
return self.__Num
num = property(getNum,setNum)
t = Test()
print("##########1")
print(t.num) #相当于调用了t.getNum()
print("##########2")
t.num = 200 #相当于调用了t.setNum(200)
print("##########3")
print(t.num)
print("##########4")
输出
##########1 100 ##########2 ---set--- ##########3 200 ##########4
用法二
class Test(object):
def __init__(self):
self.__Num = 100
@property
def num(self):
return self.__Num
@num.setter
def num(self,Num):
print("---set---")
self.__Num = Num
t = Test()
print("##########1")
print(t.num)
print("##########2")
t.num = 200
print("##########3")
print(t.num)
print("##########4")
输出
##########1 100 ##########2 ---set--- ##########3 200 ##########4
