python里协程事件循环里怎么样调用非协程函数

为了管理协程和I/O的回调函数，asyncio库的事件循环也能基于定时的方式调用普通的函数，使用call_soon()函数，例子如下：

import asyncio

import functools

def callback(arg, *, kwarg='default'):

print('callback invoked with {} and {}'.format(arg, kwarg))

async def main(loop):

print('registering callbacks')

loop.call_soon(callback, 1)

wrapped = functools.partial(callback, kwarg='not default')

loop.call_soon(wrapped, 2)

await asyncio.sleep(0.1)

event_loop = asyncio.get_event_loop()

try:

print('entering event loop')

event_loop.run_until_complete(main(event_loop))

finally:

print('closing event loop')

event_loop.close()

结果输出如下：

entering event loop

registering callbacks

callback invoked with 1 and default

callback invoked with 2 and not default

closing event loop
