如何在反应器中进行"select case"-like操作

import asyncio

class EventHandler:
    async def handle_event(self, event_type, data):
        if event_type == 'type1':
            await self.handle_type1(data)
        elif event_type == 'type2':
            await self.handle_type2(data)
        else:
            print(f"Unknown event type: {event_type}")

    async def handle_type1(self, data):
        print(f"Handling type1 event with data: {data}")
        # 处理type1事件的逻辑

    async def handle_type2(self, data):
        print(f"Handling type2 event with data: {data}")
        # 处理type2事件的逻辑

async def main():
    handler = EventHandler()
    events = [('type1', 'data1'), ('type2', 'data2'), ('unknown', 'data3')]
    
    for event_type, data in events:
        await handler.handle_event(event_type, data)

# 运行事件循环
asyncio.run(main())
