What mechanisms ensure context switching in asyncio?

In asyncio, context switching is managed by the event loop, which controls the execution of coroutines. The main mechanisms are:

• await — when the await keyword is encountered, the coroutine's execution is suspended, and control is returned to the event loop.
• Task — a wrapper around a coroutine that allows scheduling its execution.
• Event loop — monitors the readiness of tasks and switches execution between them, ensuring asynchrony.

Thus, context switching occurs when waiting for I/O operations or other asynchronous events, allowing efficient use of time without blocking.
