如何获取具有自定义属性的类的每个属性，然后在下拉列表中显示它们？

class MyClass:
    def __init__(self):
        self._property1 = "Value 1"
        self._property2 = "Value 2"

    @property
    def property1(self):
        return self._property1

    @property
    def property2(self):
        return self._property2

    def get_properties_with_custom_attribute(self):
        properties = []
        for attr in dir(self):
            if hasattr(getattr(self, attr), 'custom_attribute'):
                properties.append(attr)
        return properties


my_object = MyClass()
properties_with_custom_attribute = my_object.get_properties_with_custom_attribute()

html = "<select>"
for prop in properties_with_custom_attribute:
    html += f"<option value='{prop}'>{prop}</option>"
html += "</select>"

print(html)
