Scraping BRITANNIA Stock Market Data with Python Selenium

Web Scraping Stock Market Data with Python Selenium

Whether you’re an experienced trader or a newbie trying to get your feet wet, everyone knows that getting accurate stock market data is crucial for making informed investment decisions. In today’s digital age, most data is available online, making web scraping a valuable tool.

In this tutorial, we will focus on using Python Selenium to scrape stock market data from the National Stock Exchange (NSE) website. Specifically, we will be looking at data for the BRITANNIA trading symbol.

1. Importing Modules

To get started, you’ll need to import the necessary Python modules. This should include the Selenium module, which allows you to automate web browsing, and the time module, which helps control the speed of your program.

1.1. Example Code:

from selenium import webdriver
import time

2. Taking Input

Next, you’ll need to specify which stock symbol you want to scrape data for. In our example, we’re using BRITANNIA.

However, you can replace this with any other ticker or stock name of your choice.

2.1. Example Code:

stock_symbol = 'BRITANNIA'

3. Initializing Webdriver

Selenium requires a web browser to run.

We will be using Google Chrome for this tutorial. You can download the necessary driver from the official website (https://sites.google.com/a/chromium.org/chromedriver/downloads).

Once downloaded, you can initialize the driver with the following code:

3.1. Example Code:

driver = webdriver.Chrome('/path/to/chromedriver')

Make sure to replace “/path/to/chromedriver” with the path to your downloaded driver file.

4. Access The Website

The next step is to access the NSE website and identify the appropriate URL.

Since we are going to be scraping BRITANNIA data, the base URL will be https://www.nseindia.com/get-quotes/equity?symbol=BRITANNIA. To navigate to the website, use the following code:

4.1. Example Code:

driver.get('https://www.nseindia.com/get-quotes/equity?symbol=' + stock_symbol)

5. Find The Specific Elements We Want To Scrape

Now that we’re on the appropriate website, we need to use the browser’s inspect tool to locate the HTML element that holds the data we’re interested in.

In this case, we want to scrape the current market price of the stock. To get the element by ID, we can use the following code:

5.1. Example Code:

price_element = driver.find_element_by_id('lastPrice')

6. Store The Scraped Information In a List

Finally, we need to store the scraped information in a list, from where we can print or process it however we want.

To do so, we can use a for loop to iterate over the HTML element, and append each datum to a list. Once we have stored all the data, we can use the quit method to close the browser.

6.1. Example Code:

data_list = []
for element in price_element:
    data_list.append(element.text)

print(data_list)
driver.quit()
