Hi,

yes. By replacing highlighted in bold syntax in screener.py file we can extract yahoo data instead of quandl. After changing the code iam extracting NSE data from yahoo site without any issue. Also we need to install below packages for yahoo data.

Here is the full code:

import pandas_datareader.data as web
import datetime

# Class for analyzing and (attempting) to predict future prices
# Contains a number of visualizations and analysis methods
class Stocker():

    # Initialization requires a ticker symbol
    def __init__(self, ticker, exchange='NS'):

        # Enforce capitalization
        ticker = ticker.upper()

        # Symbol is used for labeling plots
        self.symbol = ticker

        # Use Personal Api Key
        # quandl.ApiConfig.api_key = 'YourKeyHere'

        # Retrieval the financial data
        try:
            #stock = quandl.get('%s/%s' % (exchange, ticker))
            start = datetime.datetime(2000, 1, 1)
            end = datetime.datetime.now()
            stock = web.DataReader(ticker, 'yahoo', start, end)

Tks @cnubathula !
