关于python:Python-获取一个函数的参数的默认值

能够应用 inspect 模块的 signature 办法来实现

示例代码如下：

from typing import Union
from types import UnionType
from inspect import signature
from loguru import logger


def get_score(name: str | None = None) -> float | None:
    pass


typed_signature = signature(get_score).parameters.items()


for index, (parameter_name, parameter) in enumerate(typed_signature):
    logger.debug(parameter.default)

输入
