Grazie. Questa istruzione funziona.

Buongiorno, premetto che sono un neofita.Sto cercando di scaricare dei dati da yahoo finance, seguendo alcuni tutorial da youtube. Dopo aver installato le librerie pandas_datareader, numpy,datetime ( vi indico il codice utilizzato) ho scritto questa istruzione che mi genera questo errore che non riesco a risolvere. Aggiungo che sto utilizzando Jupyter Notebook. Qualcuno può aiutarmi pls? Grazie .Gpy






from pandas_datareader import data as web

import pandas as pd

import numpy as np

from datetime import datetime

import matplotlib.pyplot as plt

plt.style.use('fivethirtyeight')




assets = ['APPL','BA','NTFLX','TSLA']




stockStartdate = '2020-01-01'




today =datetime.today().strftime('%Y-%m-%d')

today




df = pd.DataFrame()




for stock in assets:

df stock = web.DataReader(stock, data_source='yahoo',start=stockStartdate,end=today)




ERRORE:
