Question

一般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",

我想知道具体的异常名称，所以我可以添加一个专用的catch。怎么能找到它？

在捕获的异常上是否有'type'函数，或者是否应该在throw lib的源代码中找到它 - 可用here

Answer 1

这本来是一个评论，但由于它得到了很多赞成，并且OP声称这是他们正在寻找的东西，我将它作为答案重新发布：

看起来它是一个RateLimitExceeded异常。但是，如果你真的想确定，你可以这样做：

try:
    # code
except Exception as e:
    print e.__class__

这将打印出引发的异常类，这将为您提供明确的答案

Answer 2

粘贴中引发的异常是foursquare.RateLimitExceeded（如最后一行所示）。您应该能够正常捕获它，或者如果要处理模块中的所有错误，则捕获其基类foursquare.FoursquareException。

引发异常的代码只是查找从字典中引发的异常类。这不应该对你如何捕获这些错误产生任何影响。

如何知道在python中捕获哪种异常类型？
