Question

我正在运行与Rest API通信的脚本。有时，它返回一个异常，对于另外两个异常，该异常也返回During handling of the above exception, another exception occurred:。我试图使用try / except块来处理它，但是尽管导入了所有三个异常并在块中为它们编码，脚本仍然失败。

三个例外是http.client.RemoteDisconnected，urllib3.exceptions.ProtocolError和requests.exceptions.ConnectionError。

所以我的导入代码是：

from requests.exceptions import ConnectionError
from http.client import RemoteDisconnected
from urllib3.exceptions import ProtocolError

我的IDE将异常识别为已导入，因此可能没问题。我的除外代码是：

try
    [the thing]
except (InternalError, ConnectionError, RemoteDisconnected, ProtocolError) as e:
    self.lg.log(str(e) + ' ' + str(e.__traceback__) + " Some sort of connection or 
            internal error occured")

我在同一块（InternalError）上还有另一个异常，那个异常似乎可以处理。

回溯确实很长，但是我不确定哪个部分最重要，所以这就是全部
