如本question中所述,我正在使用tenacity进行重试。
玩具代码如下所示
import logging
from tenacity import retry
import tenacity
@retry(wait=tenacity.wait_incrementing(start=10, increment=10, max=100), stop=tenacity.stop_after_attempt(3))
def print_msg():
logging.info('Hello')
logging.info("World")
raise Exception('Test error')
if __name__ == '__main__':
logging.basicConfig(
format='%(asctime)s,%(msecs)d %(levelname)-8s [%(filename)s:%(lineno)d] %(message)s',
datefmt='%d-%m-%Y:%H:%M:%S',
level=logging.INFO)
logging.info('Starting')
print_msg()
输出如下所示

有人可以让我知道如何记录该异常的根本原因吗?
答案 0 :(得分:2)
您可以使用reraise=True
option,没有冗长的文档,但是您可以阅读its source:
...
File "53406953.py", line 10, in print_msg
raise Exception('Test error')
Exception: Test error
