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

Added in version 2.0.Routes, error handlers, before request, after request, and teardown functions can all be coroutine functions if Flask is installed with the async extra (pip install flask[async]). This allows views to be defined with async def and use await.@...
Asyncio is a C++20 coroutine library to write concurrent code using the await syntax, and imitate python asyncio library. Build & Run $ git clone --recursive https://github.com/netcan/asyncio.git $cdasyncio $ mkdir build $cdbuild $ cmake .. $ make -j ...
...在 await 调用时,在调用 await 函数时,如果出现非正常状况就会抛出异常,await 命令后面的 promise 对象,运行结果可能是 rejected,所以最好把await 命令放在 try...然而,为了正确地使用它们,必须完全理解 promise,因为 async/await 只不过是 promise 的语法糖,本质上仍然是 promise。
