The coroutines in asyncio run in a non-deterministic manner, and as such, there is still the possibility of our code running into race conditions regardless of the fact that it's only ever running on a single thread.

Due to the fact we can still be hit by dreaded race conditions, it's important to know how we can use the previously covered synchronization primitives in conjunction with the asyncio module.

In this section, we'll take a look at locks, events, conditions, and queues, as well as look at small examples of how these work within our event-driven Python programs. In the interest of brevity, I'm only going to give full code examples for both locks and queues as I feel these are going to be the two most commonly used concepts when it comes to synchronization between your asyncio coroutines.
