How to read AAPL data using pandas_datareader

Question

I'm trying to read Apple stock data using pandas_datareader, but I'm getting error

import pandas_datareader as web
import datetime
start = datetime(2017, 1, 1)
end = datetime(2018, 1,1)

df= web.get_data_yahoo(['AAPL'],start=start,end=end)

Error:
