Python 3.10 support

[sgtStrom]

Hello! Do you plan to add support of python 3.10? Your example won't run under python 3.10 neither using asyncio.run(main()) nor loop.run_until_complete(main()) syntax.

Hello/ Try

loop = asyncio.get_event_loop() tasks = [main()] start = time.time() loop.run_until_complete(asyncio.gather(*tasks))

[sgtStrom]

Tried this:

if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    tasks = [main()]
    loop.run_until_complete(asyncio.gather(*tasks))

but still got the same error. Here's the whole traceback:

  loop = asyncio.get_event_loop()
