A Brief Demonstration

To illustrate the power and versatility of Py2Web, let’s take a quick look at a simple code snippet. In this example, we’ll use Py2Web to scrape and extract the titles of the latest news articles from a popular news website:

“`python
from py2web import Py2Web

py2web = Py2Web()

Make an HTTP request to the news website and fetch the content

response = py2web.get(“https://www.examplenews.com”)

Render the content and extract the titles of the latest news articles

titles = py2web.render(response, “//div[@class=’news-title’]”)

Print the extracted titles

for title in titles:
print(title)
“`

This demonstrates how Py2Web simplifies the process of fetching website content and extracting useful data, making it easy to integrate web scraping functionality into your web applications.
