Mastering Python Design Patterns - Second Edition

A third example, using another third-party module

The third example uses the tenacity module. Since the retrying module has become unmaintained and there is the risk of it becoming obsolete, let's see another example where we will use its fork tenacity. We need to add the module using the pip install tenacity command. Also, the code we saw in the previous example should be updated at a couple of places. Let's see!
