python - raise ConnectionError in python2.7 -
i want raise connectionerror (a python 3 subclass) when program fails connect local service. i'm using python2.7. testing out though, looks have import module working:
>>> raise connectionerror("test") traceback (most recent call last): file "<stdin>", line 1, in <module> nameerror: name 'connectionerror' not defined how can raise type of exception?
connectionerror not exist in python 2, can see the python 2 documentation. can of course create own subclass of oserror (and call connectionerror if want), no such thing built in.
