Mark functions asasync. Call them withawait. All of a sudden, your program becomes asynchronous – it can do useful things while it waits for other things, such as I/O operations, to complete. Code written in theasync/awaitstyle looks like regular synchronous code but works very differently....

Every time we runawait(e.g.await resp.text()) we give control back to python (more specifically to theevent loopas we're going to see soon) to decide what to do in the meantime. In other words,async only "works" when you have to wait for IO operations. 🐌 Slow server (with a...
Synchronization primitives:Locks, events, conditions, and semaphoresinasynciowork like their conventional Python counterparts. One thing to keep in mind about all of these methods is that they’renotthread-safe. This isn’t an issue for async tasks running in the same event loop. But if you’...
