#python asyncio & #NetDevOps thread
Interaction with network devices is a perfect use-case for Python asyncio - a typical application waits for i/o responses from many devices. Asyncio was designed to focus on i/o heavy apps. It's efficient and enables capabilities, like
1/

...storing all connections to network devices in memory, periodically refreshing them and allows for many tasks to be executed even without a task queue (like celery), simplifying system architecture.
E.g. I can build live network diagrams in the browser within 2 seconds

2 years ago there was a problem with asyncio ecosystem for network automation, but it isn't the case anymore. We have libraries like httpx, scrapli, scrapli-netconf, FastAPI which can be used with asyncio.
I have been using python asyncio for 95%+ my apps during the last year

...I had great experience and I will keep using it for network automation.
It does require some understanding and practice, but imo, it's worth it and I can definitely recommend spending time to learn it. It will allow you to build scalable network automation apps
