老版0基础入门python45课，我设置和改变属性后，属性的值还一直是返回None
老版0基础入门python45课，我设置和改变属性后，属性的值还一直是返回None我已经使用super函数调用了基类的正常动作，为什么还是返回None?
class A():
def __init__(self,x):
self.x=100
def __getattr__(self, item):
print("没有属性时被调用啦")
def __getattribute__(self,item):
print("有属性时被调用啦")
super().__getattribute__(item)
def __setattr__(self, item, value):
print("set被调用啦")
super().__setattr__(item,value)
def __delattr__(self,item):
print("删除被调用啦")
super().__delattr__(item)
c= A(10)
print(c.x)
c.x=100
print(c.x)
b=c.x
print(c.x) 本帖最后由 heidern0612 于 2020-3-25 08:13 编辑
没有return的值。
class A():
def __init__(self,x):
self.x=x
def __getattr__(self,item):
print("check value")
def __getattribute__(self,item):
print("get value")
return super().__getattribute__(item)
def __setattr__(self, item, value):
print("set value")
return super().__setattr__(item,value)
def __delattr__(self,item):
print("del setting")
super().__delattr__(item)
c= A(10)
print(c.x)
c.x=100
print(c.x)
b=c.x
print(c.x)
class A():
def __init__(self,x):
self.x=100
def __getattr__(self, item):
print("没有属性时被调用啦")
def __getattribute__(self,item):
print("有属性时被调用啦")
return super().__getattribute__(item)
def __setattr__(self, item, value):
print("set被调用啦")
super().__setattr__(item,value)
def __delattr__(self,item):
print("删除被调用啦")
super().__delattr__(item)
c= A(10)
print(c.x)
c.x=100
print(c.x)
b=c.x
print(c.x)
