python - 如何获取 @property getter/setter 的类型？

Question

以下面的类和类实例为例:

class NewClass:

    def __init__(self, a):
        self.number = a

    def func(self):
        return

    @property
    def test_property(self):
        return self.test_property


new = NewClass(1)

尝试获取属性和方法的类型是有效的:

>>> print(type(new.number))
int
>>> print(type(new.func))
method

获取 @property 的类型会导致递归错误:

>>> print(type(new.test_property))
: maximum recursion depth exceeded while calling a Python object
return.RecursionError

如何获取@property属性的类型？

也许您想这样定义您的属性:

class NewClass:

    def __init__(self, a):
        self.number = a

    def func(self):
        return

    @property
    def test_property(self):
        #return self.test_property  # Always going to call itself forever
        return self.number          # Maybe this is what you meant?
