TypeError: '_SessionRequestContextManager' object is not iterable

From this tutorial for multiple asynchronous get requests I copied and ran the following code:

import asyncio    import aiohttp    def fetch_page(url, idx):        url = 'https://yahoo.com'      response = yield from aiohttp.request('GET', url)        if response.status == 200:          print("data fetched successfully for: %d" % idx)      else:          print("data fetch failed for: %d" % idx)          print(response.content, response.status)    def main():        url = 'https://yahoo.com'      urls = [url] * 100        coros = []      for idx, url in enumerate(urls):          coros.append(asyncio.Task(fetch_page(url, idx)))        yield from asyncio.gather(*coros)    if __name__ == '__main__':        loop = asyncio.get_event_loop()      loop.run_until_complete(main())  

However, I get the following errors:

RuntimeWarning: coroutine 'ClientSession._request' was never awaited
