python - Python重试改变行为

Question

我有一个用@retry 装饰的函数（来自重试库），如果这是重试，我想改变函数的行为以记录更多信息 - 是否有内置的方法来处理这个？

即是这样的：

from retrying import retry

@retry
def foo():
    if retry:
        log('retrying')
    throw Exception

This library is not updated. You can use tenacity.

doc: https://tenacity.readthedocs.io/en/latest/

You can log before or after

import logging

logging.basicConfig(stream=sys.stderr, level=logging.DEBUG)

logger = logging.getLogger(__name__)

@retry(stop=stop_after_attempt(3), before=before_log(logger, logging.DEBUG))
def raise_my_exception():
    raise MyException("Fail")
