I know I'm missing something basic here.

Prerequisite: I'm not allowed to edit '__main__'.

Given that prerequisite, how can I print x as soon as fun() returns something ? I know I can use asynio.gather, but that would mean waiting for everything to complete.

import asyncio


async def fun(n):
    for i in range(n):
        await asyncio.sleep(i*.1)
        yield i


def main(n):
    yield from asyncio.run(fun(n))


if __name__ == '__main__':
    n = 5
    for x in main(n):
        print(x)

Could you please explain in more detail what you need and why the code you've provided doesn't work as you want it to? – Yevhen Kuzmovych Mar 05 '23 at 14:57

`asyncio.run` is sync function, you can't 'yield from' it. – Artiom Kozyrev Mar 05 '23 at 14:58
I just want to print/use the output from `fun()` in `__main__` as soon as it yields an item. – Jibin Mar 05 '23 at 15:17
