I dispute the "better" assertion. Anyhow, I don't know how familiar or not you are with sync code, but it fully supports background jobs using queues with threads/interpreters/processes. It has been around for decades, far longer than async.

Also, it is okay to run something in the foreground. Not everything needs to run in the background. Sometimes it's better to wait and have assurance of completion.

There is no natural parallelism of async code in Python. The coroutines run in a single thread.
