如何知道在Python中捕获哪种异常类型？

Question

通用异常捕获器记录以下异常：

> Traceback (most recent call last):   File "4sq.py", line 37, in
> <module>
>     checkin = client.checkins()   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 416, in __call__
>     return self.GET('{CHECKIN_ID}'.format(CHECKIN_ID=CHECKIN_ID), params, multi=multi)   File
> "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 217, in GET
>     return self.requester.GET(self._expanded_path(path), *args, **kwargs)   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 163, in GET
>     return self._request(url)   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 200, in _request
>     return _request_with_retry(url, data)['response']   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 696, in _request_with_retry
>     return _process_request_with_httplib2(url, data)   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 719, in _process_request_with_httplib2
>     return _check_response(data)   File "/usr/local/lib/python2.7/dist-packages/foursquare-20120716-py2.7.egg/foursquare/__init__.py",
> line 742, in _check_response
>     raise exc(meta.get('errorDetail')) RateLimitExceeded: Quota exceeded

我想知道具体的异常名称，以便我可以为其添加专用的捕获。怎么才能找到呢？

捕获的异常是否有“类型”函数，或者应该在抛出库的源代码中找到它 - 可以在此处找到

粘贴中引发的异常是foursquare.RateLimitExceeded（如最后一行所述）。您应该能够正常捕获它，或者foursquare.FoursquareException如果您想处理模块中的所有错误，则捕获它的基类。

引发异常的代码只是从字典中查找要引发的异常类。这不应该对您捕获这些错误的方式产生任何影响。
