I have written some simple code to iterate through a group of lists I am analyzing, and I discovered this error – module ‘numpy’ has no attribute ‘concat’, in this case would there be a solution?

`

The stocks we’ll use for this analysis

tech_list = [‘AMZN’, ‘NVDA’, ‘VOO’, ‘QQQ’]

Set up End and Start times for data grab

tech_list = [‘AMZN’, ‘NVDA’, ‘VOO’, ‘QQQ’]

end = datetime.now()
start = datetime(end.year – 1, end.month, end.day)

for stock in tech_list:
globals()[stock] = yf.download(stock, start, end)

company_list = [AMZN, NVDA, VOO, QQQ]
company_name = [“AMAZON”, “NVIDIA”, “Vanguard S&P 500”, “Invesco QQQ”]

for company, com_name in zip(company_list, company_name):
company[“company_name”] = com_name

df = pd.concat(company_list, axis=0)
df.tail(10)

AttributeError: module ‘numpy’ has no attribute ‘concat’
