How to find yfinance ticker symbols for Indian stocks?

You can use Yahoo Finance Python package to get lots of financial information about a given stock.

But people often wonder how to find the ticker symbols for a listed NSE companies. 

For example, you want to find the stock prices for HDFC Bank. So, you write -

import yfinance as yahoo_finance


def get_ticker_daily_price(symbol, period="1mo"):
    tickerBase = yahoo_finance.Ticker(symbol)
    data = tickerBase.history(period)
    print(data)


if __name__ == '__main__':
    get_ticker_daily_price('HDFCBANK')  # incorrect symbol

And you get the below error -

- HDFCBANK: No data found, symbol may be delisted
Empty DataFrame
Columns: [Open, High, Low, Close, Adj Close, Volume]
Index: []

So, you wonder how to find the proper "symbol" for HDFC bank.

Well, it's easy.

1. Check the name of the ticker in Official NSE's list. For a direct link, use this.
2. Add .NS at the end of the ticker.

So, for HDFCBANK, it will be HDFCBANK.NS and so on.
