Setting freq of pandas DatetimeIndex after DataFrame creation

Question

Im using pandas datareader to get stock data.

import pandas as pd
import pandas_datareader.data as web
ABB = web.DataReader(name=\'ABB.ST\', 
                           


        

Answer 1

Try:

ABB = ABB.asfreq('d')

This should change the frequency to daily with NaN for days without data.

Also, you should rewrite your for-loop as follows:

for index, row in ABB.iterrows():
    print(ABB.loc[[index + pd.Timedelta(days = 1)]])

Thanks!
