why am I getting a "TypeError: String indices Must be integer" Message when trying to access Yahoo Finance? [duplicate]

Question

I'm following along with a Udemy course for Python & Finance, unfortunately hit a wall whilst trying to call stock data from yahoo using pandas_dataReader.

Here's my code copied directly from jupyter notebook

import numpy as np
import pandas as pd

from pandas_datareader import data as wb
PG = wb.DataReader('PG', data_source='yahoo', start='1995-1-1')

this returns the following - rather lengthy - error message:

---------------------------------------------------------------------------

TypeError: string indices must be integers

This is a known bug in pandas-datareader. Take a look at this issue: GitHub Issue – Jackshaft

Does this answer your question? "TypeError: string indices must be integers" when getting data of a stock from Yahoo Finance using Pandas Datareader – Healion

Answer 1

as @Clasherkasten points out in their comment, you can:

import numpy as np
import pandas as pd

import yfinance as yf
yf.pdr_override() # <== that's all it takes :-)
from pandas_datareader import data as pdr

PG = pdr.get_data_yahoo('PG', start='1995-1-1')

Or else, if you still want to use your code you can get the same information by replacing your data_source = 'yahoo' with data_source = 'stooq'

The information on stooq data source can be found here.
