[FIXED] async_generator' object is not iterable

Issue

I need to return a value in async function. I tried to use synchronous form of return:

import asyncio

async def main():
    for i in range(10):
        return i
        await asyncio.sleep(1)

print(asyncio.run(main()))

output:

0 [Finished in 204ms]

But it just return value of the first loop, which is not expexted. So changed the code as below:

import asyncio

async def main():
    for i in range(10):
        yield i
        await asyncio.sleep(1)

for _ in main():
    print(_)

output:

TypeError: 'async_generator' object is not iterable

by using async generator I am facing with this error. How can I return a value for every loop of async function?

Thanks

Solution

You need to use an async for which itself needs to be inside an async function:

async def get_result():
    async for i in main():
        print(i)

asyncio.run(get_result())
