Simulating Multiple Servers

[JiaNannnn]

Hi Guys, I'm trying to simulate multiple servers using asyncio.

@uamethod
def func(parent, value):
    return value * 2

async def main():
  server setups...
async def main2():
  server setups...

if __name__=='__main__':
     asyncio.run(main())
     asyncio.run(main2())

Is simulating multiple servers using Asyncio possible? if so, did I make any mistakes?

Yes. This is no problem. Yes your code is completely wrong. Take some python asyncio tutorial first

Yeap, just came across this library yesterday. You are right, should have taken more time to read up and try out the tutorials.

each Server needs to be in a own asyncio task!

e.g.:

async def server1():
    # create the server here
    pass

async def server2():
    # create the server here
    pass

async def main():
    task1 = asyncio.create_task(server1())
    task2 = asyncio.create_task(server2())
    await asyncio.gather(task1, task2)

if __name__ == "__main__":
    # since python 3.8 has changed the default event loop
    # only if your on windows
    if sys.platform.lower() == "win32" or os.name.lower() == "nt":
        from asyncio import (
            set_event_loop_policy,
            WindowsSelectorEventLoopPolicy
        )
        set_event_loop_policy(WindowsSelectorEventLoopPolicy())
    asyncio.run(main())

Thank you so much!
