Get all @properties from a Python Class [duplicate]

问题

This question already has answers here:

In a Python object, how can I see a list of properties that have been defined with the @property decorator? (5 answers)

Closed 7 days ago.

In Python, how can I get all properties of a class, i.e. all members created by the @property decorator?

There are at least two questions^{[1, 2]} on stackoverflow which confound the terms property and attribute, falsely taking property as a synonym for attribute, which is misleading in Python context. So, even though the other questions' titles might suggest it, they do not answer my question.

回答1:

We can get all attributes of a class cls by using cls.__dict__. Since property is a certain class itself, we can check which attributes of cls are an instance of property:

from typing import List


def properties(cls: type) -> List[str]:
    return [
        key
        for key, value in cls.__dict__.items()
        if isinstance(value, property)
    ]
