使用python-asyncio，我如何读取urls而不是在main函数中列出urls？

import asyncio
import aiohttp

async def fetch(session, url):
    async with session.get(url) as response:
        return await response.text()

async def main():
    urls = ['https://www.example.com', 'https://www.example.org', 'https://www.example.net']

    async with aiohttp.ClientSession() as session:
        tasks = []
        for url in urls:
            task = asyncio.create_task(fetch(session, url))
            tasks.append(task)

        # 并发执行所有的任务
        responses = await asyncio.gather(*tasks)

        # 处理所有的响应
        for response in responses:
            print(response)

asyncio.run(main())
