In this blog post, we will learn how to scrape stock prices from a financial website using Python. We will be using the requests
and BeautifulSoup
libraries to fetch the HTML content of a webpage and then parse it to extract the desired data.
1. Import necessary libraries
Python
import requests
from bs4 import BeautifulSoup
import json
requests
: This library is used to make HTTP requests to websites and retrieve their content.BeautifulSoup
: This library is used to parse HTML content and extract data from it.json
: This library is used to work with JSON data.2. Obtain a Quick Scraper Access Token
To use the Quick Scraper API, you will need to obtain an access token. You can get a free token by signing up for an account on [invalid URL removed].
3. Set up the API request
Python
access_token = 'YOUR_ACCESS_TOKEN' # Replace with your actual access token
url = f"<https://api.quickscraper.co/parse?access_token={access_token}&url=https://seekingalpha.com/symbol/AAPL>"
We are using the Quick Scraper API to simplify the process of fetching the HTML content of the target webpage. The API takes two arguments:
access_token
: Your Quick Scraper access token.url
: The URL of the webpage you want to scrape.4. Make the API request and parse the HTML content
Python
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
requests.get(url)
method sends a GET request to the specified URL and retrieves the HTML content of the webpage.BeautifulSoup
library is used to parse the HTML content into a tree-like structure that can be easily navigated.5. Extract the stock data
Python
symbol_name = soup.select_one('div[data-test-id="symbol-name"] h1').text.strip()
symbol_price = soup.select_one('span[data-test-id="symbol-price"]').text.strip()
soup.select_one('div[data-test-id="symbol-name"] h1')
selects the first <h1>
element within a div
element that has the attribute data-test-id
set to "symbol-name"
. This element most likely contains the name of the stock..text.strip()
extracts the text content from the selected element and removes any leading or trailing whitespace characters.soup.select_one('span[data-test-id="symbol-price"]').text.strip()
.6. Save the data to a JSON file
Python
data = {
"name": symbol_name,
"price": symbol_price
}
with open('symbol_data.json', 'w') as f:
json.dump(data, f)
print("Data saved to symbol_data.json")
data
to store the scraped stock data.json.dump
function is used to convert the Python dictionary to a JSON string and write it to a file named symbol_data.json
.7. Scheduling the script to run daily
To scrape stock prices every day, you can use a task scheduler like cron on Linux/macOS or Task Scheduler on Windows. You can set the scheduler to run the Python script at a specific time each day.
Additional Considerations
