如何知道在python中捕获哪种异常类型？

常规异常捕获程序记录以下异常：

我想知道具体的异常名称，这样我就可以添加一个专用的捕获。 如何找到它

---

捕获的异常上是否有“type”函数，或者是否应该在抛出库的源代码中找到它-可用

粘贴中引发的异常是

foursquare.ratelimited

（如最后一行所述）。如果要处理模块中的所有错误，您应该能够正常捕获它，或者捕获它的基类

foursquare.FoursquareException

---

引发异常的代码只是从字典中查找要引发的异常类。这不应该对你如何发现这些错误有任何影响。

这本来是一个评论，但因为它获得了很多选票，OP声称这就是他们所寻找的，我将它作为一个答案重新发布：

看起来这是个例外。不过，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，它将给您一个明确的答案

看起来像是一个

ratelimited

异常。不过，可以肯定的是，我会将它包装在一个

try

/

中，例外情况除外，作为e

并打印

e。那会给你一个明确的答案谢谢你一直在寻找类似e的东西！
