Pulling stock information using pandas datareader

Question

I am using pandas datareader to pull stock information for a given range of dates. For example:

import pandas_datareader.data as web
import datetime as dt

start = dt.datetime(2018,3,26)
end = dt.datetime(2018,3,29)

web.DataReader('IBM','yahoo', start, end).reset_index()

This returns the following dataframe for IBM:

This contains the information I am looking for, but I would like to automatically iterate through multiple stock tickers (instead of manually changing the stock ticker). Ideally I could loop this code through a list of desired stock tickers.

Answer 1

Here is another way, creating your dataframe directly:

tickers = ['IBM','AAPL']

df = pd.concat([web.DataReader(ticker,'morningstar', start, end) for ticker in tickers]).reset_index()

Which returns:
