Extracting live stock price

There are two modules in the yahoo_fin package, stock_info and options. We are going to use the stock_info module to get the live stock price.

Step 1:- Import stock_info module from yahoo_fin package.

Step 2:- Insert the ticker symbol of a stock followed by a suffix “.NS” as a parameter in the function get_live_price().

In the above example, the ticker symbol of Larsen and Toubro Limited followed by suffix “.NS” is given as a parameter to the function get_live_price()

To iterate, the parameter of get_live_price() function must be:-

valid_stock_ticker_symbol.NS

The “.NS” suffix represents the National Stock Exchange.
