import aiohttp, asyncio

async def fetch(url):
    async with aiohttp.ClientSession() as session:
        async with session.get(url) as resp:
            return await resp.text()

async def main():
    urls = ["http://example.com"] * 5
    results = await asyncio.gather(*(fetch(u) for u in urls))
    print(results)

asyncio.run(main())
