get "DeprecationWarning: There is no current event loop" warning

Run this script in Python3.10, we will get "DeprecationWarning: There is no current event loop" warning.

That's caused by

loop = asyncio.get_event_loop()

Suggest to use this

loop = asyncio.new_event_loop()
asyncio.set_event_loop(loop)

And, here

class UDPReceiver:

    @staticmethod
    def create(loop, local_addr, server, verbose):
        task = asyncio.Task(loop.create_datagram_endpoint(
            lambda: UDPReceiver(server=server, verbose=verbose),
            local_addr=local_addr, allow_broadcast=True))
        _, udpreceiver = loop.run_until_complete(task)
        return udpreceiver

It creates a Task instance without specifying event loop, that will cause it to use current running loop which does not exists at that time. It will also bring "DeprecationWarning: There is no current event loop" warning.

Suggest to change to this

class UDPReceiver:

    @staticmethod
    def create(loop, local_addr, server, verbose):
        coro = loop.create_datagram_endpoint(
            lambda: UDPReceiver(server=server, verbose=verbose),
            local_addr=local_addr, allow_broadcast=True)

        task = asyncio.Task(coro,loop=loop)

        _, udpreceiver = loop.run_until_complete(task)
        return udpreceiver
