Why am I seeing "TypeError: string indices must be integers" in this situation?

im trying to predict stock market movement but in the start i’m stuck in this error: "TypeError: string indices must be integers"

the code that i have problem with is:

import pandas_datareader as web
df = web.DataReader('AAPL', data_source='yahoo', start='2012-01-01', end='2019-12-17')

TypeError: string indices must be integers

>Solution :

The YahooDailyReader seems to be broken from pandas_datareader. However, you can use yfinance module directly:

import yfinance as yf

df = yf.download('AAPL', start='2012-01-01', end='2019-12-17')

Output:

>>> df
                 Open       High        Low      Close  Adj Close     Volume
Date
