In a very simple sense, it does this by having an event loop execute a collection of tasks, with a key difference being that each task chooses when to yield control back to the event loop. Asyncio is a good fit for IO-bound and high-level structured network code. Boto3 (AWS Python SDK) falls into this category. A lot of existing libraries are not ready to be used with asyncio out of the box. They may block, or depend on concurrency features not available through the module. It’s still possible to use those libraries in an application based on asyncio by using an executor from concurrent.futures to run the code either in a separate thread or a separate process. The run_in_executor() method of the event...
