避免“太宽泛的例外条款"； PyCharm中的警告

本文介绍了避免“太宽泛的例外条款"； PyCharm中的警告的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在脚本的顶层编写一个异常子句，我只希望它记录发生的任何错误.烦人的是，PyCharm抱怨我是否抓住了Exception.

I'm writing an exception clause at the top level of a script, and I just want it to log whatever errors occur. Annoyingly, PyCharm complains if I just catch Exception.

import logging

logging.basicConfig()

try:
    raise RuntimeError('Bad stuff happened.')
except Exception:  # <= causes warning: Too broad exception clause
    logging.error('Failed.', exc_info=True)

此处理程序有问题吗?如果没有，我该如何告诉PyCharm闭嘴?

Is there something wrong with this handler? If not, how can I tell PyCharm to shut up about it?

推荐答案

来自 Joran 的评论:您可以使用# noinspection PyBroadException告诉PyCharm您可以使用此异常子句.这是我最初想要的，但是我错过了抑制显示的选项检查在建议菜单中.

From a comment by Joran: you can use # noinspection PyBroadException to tell PyCharm that you're OK with this exception clause. This is what I was originally looking for, but I missed the option to suppress the inspection in the suggestions menu.

import logging

logging.basicConfig()

# noinspection PyBroadException
try:
    raise RuntimeError('Bad stuff happened.')
except Exception:
    logging.error('Failed.', exc_info=True)

如果您甚至不想记录该异常，而只是想在不抱怨PyCharm的情况下抑制该异常，则Python 3.4中有一个新功能: contextlib.suppress() .

If you don't even want to log the exception, and you just want to suppress it without PyCharm complaining, there's a new feature in Python 3.4: contextlib.suppress().

import contextlib

with contextlib.suppress(Exception):
    raise RuntimeError('Bad stuff happened.')

这等效于此:

try:
    raise RuntimeError('Bad stuff happened.')
except Exception:
    pass
