Historic Stock Prices in Pandas DataFrame

Question

This code is able to get the history of stock prices and the dates are set as the index of the DataFrame.

How can I pass the dates (index) to a column and add the ticker out of iteration to another column?

import yfinance as yf
import pandas as pd

tickers = ["GOOG","AMZN"]

df2 = pd.DataFrame()

for ticker in tickers:
    try:
        tkr = yf.Ticker(ticker)
        hist = tkr.history(period="1y")
        df2 = df2.append(hist)
        print(df2)

Result:

               Open     High      Low  ...   Volume  Dividends  Stock Splits
Date                                   ...                                  
2019-06-06  1044.99  1047.49  1033.70  ...  1703200          0             0
2019-06-07  1050.63  1070.92  1048.40  ...  1802400          0             0
2019-06-10  1072.98  1092.66  1072.32  ...  1464200          0             0

Objective:

Ticker     Date     Open     High      Low  ...   Volume  Dividends  Stock Splits

GOOG 2019-06-06  1044.99  1047.49  1033.70  ...  1703200          0             0
GOOG 2019-06-07  1050.63  1070.92  1048.40  ...  1802400          0             0
GOOG 2019-06-10  1072.98  1092.66  1072.32  ...  1464200          0             0

Answer 1

You can just do this:

for ticker in tickers:
    tkr = yf.Ticker(ticker)
    hist = tkr.history(period="1y")
    df2 = df2.append(hist)
    df2['Ticker'] = ticker

    print(df2.reset_index())
