there're exactly/only two reason to use async-based concurrency over thread-based concurrency: 1.Asyncio offers a safer alternative to preemptive multitasking (i.e., using threads), thereby avoiding the bugs, r
Python async/await example IIWith asyncio.run, we simplify the code. The function creates an event loop, schedules the coroutines and in the end closes the loop. simple2.py #!/usr/bin/python import asyncio async def add(x, y): return x + y async def get_results(): res1 = await ...
Chapter 4. 20 Asyncio Libraries You Aren’t Using (But…Oh, Never Mind) In this chapter, we look at case studies using the new Python features for async programming. We’ll be making … - Selection from Using Asyncio in Python [Book]

Withqasync, you can useasynciofunctionalities directly inside Qt app's event loop, in the main thread. Using async functions for Python tasks can be much easier and cleaner than usingthreading.ThreadorQThread. If you need some CPU-intensive tasks to be executed in parallel,qasyncalso got that...
