How to properly download stocks data in python

I have been trying to extract stock prices using pandas_datareader. data, but I kept receiving an error message.

I have checked other threads relating to this problem and, I have tried downloading data reader using conda install DataReader and also tried pip install DataReader.

import pandas as pd

 import datetime

from pandas import Series,DataFrame

import pandas_datareader.data as web

pandas_datareader.__version__

'0.6.0'

start=datetime.datetime(2009,1,1)

end=datetime.datetime(2019,1,1)

df=web.DataReader( 'AT&T Inc T',start,end)

df.head()

My expected result should be a data frame with all the features and rows of the stock.

Below is the error message I got: Please, how do I fix this problem?

Thanks.
