在视频里，说property属性对象提供了getter、setter和deleter三个方法，这些方法对应property()函数的三个参数接口，实际上是不是就是下面这三个？
def __get__(self, instance, owner):
        print(f'get~\nself -> {self}\ninstance -> {instance}\nowner -> {owner}')
def __set__(self, instance, value):
        print(f'set~\nself -> {self}\ninstance -> {instance}\nvalue -> {value}')
def __delete__(self, instance):# 不要混淆__del__()
        print(f'delete~\nself -> {self}\ninstance -> {instance}')

class MyClass:
    def __init__(self):
        self._x = None
   
    @property
    def x(self):
        return self._x
   
    @x.setter
    def x(self, value):
        self._x = value
   
    @x.deleter
    def x(self):
        del self._x
这里的为啥不是@x.__set__(self, instance, value)
和@x.__delete__(self, instance)？

class MYPropertyL:
    def __init__(self, fget=None, fset=None, fdel=None):
        self.fget = fget
        self.fset = fset
        self.fdel = fdel
    def __get__(self, instance, owner):
        return self.fget(instance)
    def __set__(self, instance, value):
        self.fset(instance, value)
    def __delete__(self, instance):
        self.fdel(instance)
    def getter(self, func):
        self.fget = func
        return self
    def setter(self, func):
        self.fset = func
        return self
    def deleter(self, func):
        self.fdel = func
        return self
在getter(self, func) deleter(self, func) 和setter(self, func)里，为什么还要都return self？

class PropertyL:
    def __init__(self, fget=None, fset=None, fdel=None):
        self.fget = fget
        self.fset = fset
        self.fdel = fdel
    def __get__(self, instance, owner):
        return self.fget(instance)
    def __set__(self, instance, value):
        self.fset(instance, value)
    def __delete__(self, instance):
        self.fdel(instance)
    def getter(self, func):
        self.fget = func
        return self
    def setter(self, func):
        self.fset = func
        return self
    def deleter(self, func):
        self.fdel = func
        return self
是不是通过装饰器   修改了    self.fget  self.fset   self.fdel 属性值并将其变成了函数，再通过
    def __get__(self, instance, owner):
        return self.fget(instance)
    def __set__(self, instance, value):
        self.fset(instance, value)
    def __delete__(self, instance):
        self.fdel(instance)
这几个三个函数的触发条件，才形成对拦截对象属性的读取、写入和删除操作

class PropertyL:
    def __init__(self, fget=None, fset=None, fdel=None):
        self.fget = fget
        self.fset = fset

    def __get__(self, instance, owner):

        self.fset(instance, value)

    def getter(self, func):
        self.fget = func
        return self
    def setter(self, func):
        self.fset = func
        return self
    def deleter(self, func):
        self.fdel = func
        return self
是不是通过装饰器   修改了    self.fget  self.fset   self.fdel 属性值并将其变成了函数？

再去执行对拦截对象属性的读取、写入和删除操作的是
    def __get__(self, instance, owner):
      
    def __set__(self, instance, value):
      
    def __delete__(self, instance):
是上面这三个？
   
def getter(self, func):

def setter(self, func):
   
def deleter(self, func):
还是什么这三个？

上面的读取、写入和删除操作触发条件有哪些?
@FishC

亦又

- `__get__(self, instance, owner)`：用于拦截对属性的读取操作。
- `__set__(self, instance, value)`：用于拦截对属性的写入操作。
- `__delete__(self, instance)`：用于拦截对属性的删除操作。
