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


async def main():
    coros = [
        download('https://www.python.org/'),
        download('https://www.python.org/'),
        download('https://www.python.org/'),
        download('https://www.python.org/'),
        download('https://www.python.org/'),
        download('https://www.python.org/'),
    ]

    await asyncio.gather(*coros)

    assert calls == 1


loop = asyncio.get_event_loop()
