Handling just one exception code

Question

I have a question regarding try/except. I have an exception (lets call it FooException) that has a status_code in it. I want to handle the exception just if the status_code is 200.

I would do something like:

try:
    ...
except FooException as ex:
    if ex.status_code == 200:
        # do something
    else:
        # do something else

Is there any other way or this one should go fine?

Thanks!

that's fine... Have your else: simply call raise, and it will simply re-raise the current exception, to be handled elsewhere. (or pass if you simply want to ignore.)

Yeah. Thanks, I was sure that works, but didn't know if there was another (more pythonic) way.

You could always create a subclass of FooException, say, Foo200Exception have your code throw that exception, but I'm all for readability and simplicity. Invent new stuff right before you need it & not before.
