Step1: Set Up Your System :-
- Playwright is designed to work with Python 3.7 and above, and it does not support Python 2. Python 2 has reached its end of life, and most modern libraries, including Playwright, do not support it. you can install the package for Linux, Windows, and OS X.
Step2: Install Playwright :-
Example Usage :
5. Pyppeteer
Overview :
- Pyppeteer is a Python port of Puppeteer, the popular headless Chrome Node.js API. It provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol.
Key Features :
- Headless Browser: Ideal for scraping content that requires a full browser environment.
- DevTools Protocol: Offers powerful features through the Chrome DevTools Protocol.
- JavaScript Execution: Handles pages with dynamic content efficiently.
Web Scraping with Pyppeteer :
Pyppeteer is a Python port of Puppeteer, which is a Node library that provides a high-level API to control headless Chrome or Chromium over the DevTools Protocol. It allows you to perform web scraping and browser automation tasks similar to Playwright and Selenium.
Step1: Set Up Your System :-
Pyppeteer, unfortunately, does not support Python 2. It's designed to work with Python 3 only. This is because Python 2 has reached its end-of-life and is no longer maintained or supported as of January 1, 2020. As a result, most modern libraries and tools, including Pyppeteer, are developed exclusively for Python 3. you can install the package for Linux, Windows, and OS X.
Step2: Install Pyppeteer :-
