import asyncio
import ansq
async def main():
reader = await ansq.create_reader(
topic="example_topic",
channel="example_channel",
)
async for message in reader.messages():
print(f"Message: {message.body}")
await message.fin()
await reader.close()
if __name__ == "__main__":
asyncio.run(main())

import asyncio
import ansq
async def main():
writer = await ansq.create_writer()
await writer.pub(
topic="example_topic",
message="Hello, world!",
)
await writer.close()
