在 for 循环中构建和构造数据框

Question

我有以下代码

for x in player_ids:
    nest_asyncio.apply()
    async def main():
        async with aiohttp.ClientSession() as session:
            understat = Understat(session)
            player_shots = await understat.get_player_shots(
                x, 
                {"season": "2020", "situation": "OpenPlay"})
            df = pd.DataFrame(player_shots)
            return df

loop = asyncio.get_event_loop()
df=loop.run_until_complete(main())

对于循环的每次迭代，我想将数据添加到数据帧中。这样做的方法是创建一个空的数据框并附加吗？
