   Looking at Before and After Retry, and Logging it is possible to execute an action:

   1. Before any attempt of calling the function (before action)
   2. After a call that failed (including after the last attempt) (after action)
   3. After a failure that is going to be retried (but before the sleep) (before_sleep action)

   None of these matches your use case exactly, but 1 (the before action) sounds like it might be the closest.

   I guess you can either restructure your code to have the connection for the first attempt also established in this action, or to no-op the action on the first attempt.

   Sounds like the enhancement that would meet your needs of executing an action before any retry would be:

   4. Ability to specify an after_sleep action

   Unfortunately this is not currently supported, but I'm sure a PR to add this would be considered.

   Seems like a duplicate of #298.

   I don't find a corresponding PR.

   Use the before_sleep callback to run a function between retries:

   def reconnect(retry_state):
       reinitialise_connection()
   
   @retry(before_sleep=reconnect)
   def do_work():
       ...

   Closing as a usage question (duplicate of #298).
