如何在 asyncio python 中使用返回

Question

import asyncio


def test_async_call(test):
    return test

def test_another_async_call(xyz):
    return xyz

async def first_one():
    return test_async_call('hello')
async def second_one():
    return test_another_async_call('hi')

async def final_one():
    tasks = first_one(), second_one()
    await asyncio.gather(*tasks)

I am pretty new to asyncio and trying to call multiple functions in async, is the above way not correct? How can i call multiple functions in async way.

Answer 1

You can do the following (this is just a concept; this will not work how you want in your program)

async def main():
    return "hi"

Then, start the async program by doing this:

loop = asyncio.get_event_loop()
result = loop.run_until_complete(main())

Now, result will be equal to "hi" . The way I'd recommend starting further async functions is to simply do:

variablename = await asyncfunction(param)

Hope this helps.
