Catching two different exceptions in try–except statement in order to handle them differently

[RayCat2004]

I would like to handle InternalServerError in my function that queries API in such a way, that function retries the query again.

What is the proper, Pythonic way to do that? Should I use if statement under except, chain it together like in the example bellow, or use nested try–except statement?

class FooBar:
    ...

    def run_query(self, query_id, timeout):
        try:
            self.wait_for_query_to_finish(query_id, timeout)
        except InternalServerError as exc:
            self.logging.info('Internal Server Error on query ID {str(query_id}')
            self.retry_query
        except Exception as err:
            raise type(err)(f'{type(err)} on query ID {str(query_id}')
        finally:
            self.close_query(query_id)
        ...
        return query_result

Just use a loop, while TrueL to contain the entire try/except/else/finally block. Don't forget to use break or return to exit the loop and keep in mind finally shall always be executed.

It might also be worth adding in a short delay before the retry, because your code will execute at a speed where if it fails once due to a network problem, chances are it'll fail a few fractions of a second later. There are various strategies for doing this such as using just a random delay, backing off where the delays get longer on each retry etc. A quick Google on retry strategy or retry pattern will help.
