I need a program that uses asyncio to grab data for multiple stocks from AlphaVantage API. I have tried multiple versions of python and still get errors.

api_key = "YOUR_API_KEY"

import asyncio
from alpha_vantage.async_support.timeseries import TimeSeries

symbols = ['AAPL', 'GOOG', 'TSLA', 'MSFT']


async def get_data(symbol):
    ts = TimeSeries(key=api_key)
    data, _ = await ts.get_quote_endpoint(symbol)
    await ts.close()
    return data

loop = asyncio.get_event_loop()
tasks = [get_data(symbol) for symbol in symbols]
group1 = asyncio.gather(*tasks)
results = loop.run_until_complete(group1)
loop.close()
print(results)

This is the error I am getting:

Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x0000021D65CBBDC0>
Traceback (most recent call last):
