The asyncio module allows for the implementation of asynchronous programming using a combination of the following elements:

• Event loop: The asyncio module allows an event loop per process.
• Coroutines: A coroutine is a generator that follows certain conventions. Its most interesting feature is that it can be suspended during execution to wait for external processing (the some routine in I/O) and return from the point it had stopped when the external processing was done.
• Futures: Futures represent a process that has still not finished.
• Tasks: This is a subclass of asyncio.Future that encapsulates and manages coroutines. We can use the asyncio.Task object to encapsulate a coroutine.
