Yet another retry implementation.

retry_toolkit

(Yet Another) Retry implementation for python.

Do you have code that may be subjected to intermittent failures? Then you should have a retry wapper for it. This module includes a simple retry decorator (factory) you can use. Or peek inside and copy the implementation into your own project where you can make your own tweaks.
