You have to catch the exception and based on which error, reconnect or to do something else. Whether it is a connection time out, or a network problem or the MySQL had to be restarted.

The below (pseudoish) code shows how you could do that, but there is more to it. You'll want to try a few times and then bail out, or maybe try every 2 minutes or so.

while True:
    try:
        # do your database stuff
    except peewee.OperationalError as exc:
        # Oops! We have to try to reconnect

Does not really matter whether you use an ORM or not. However, an ORM might offer this functionality.
