Python Web Scraping Cookbook

By: Michael Heydt

Overview of this book

Python Web Scraping Cookbook is a solution-focused book that will teach you techniques to develop high-performance scrapers and deal with crawlers, sitemaps, forms automation, Ajax-based sites, caches, and more. You'll explore a number of real-world scenarios where every part of the development/product life cycle will be fully covered. You will not only develop the skills needed to design and develop reliable performance data flows, but also deploy your codebase to AWS. If you are involved in software engineering, product development, or data mining (or are interested in building data-driven products), you will find this book useful as each recipe has a clear purpose and objective. Right from extracting data from the websites to writing a sophisticated web crawler, the book's independent recipes will be a godsend. This book covers Python libraries, requests, and BeautifulSoup. You will learn about crawling, web spidering, working with Ajax websites, paginated items, and more. You will also learn to tackle problems such as 403 errors, working with proxy, scraping images, and LXML. By the end of this book, you will be able to scrape websites more efficiently and able to deploy and operate your scraper in the cloud.

Ripping an MP4 video to an MP3

Now let's examine how to rip the audio from an MP4 video into an MP3 file. The reasons you may want to do this include wanting to take the audio of the video with you (perhaps it's a music video), or you are building a scraper / media collection system that also requires the audio separate from the video.

This task can be accomplished using the moviepy library. moviepy is a neat library that lets you do all kinds of fun processing on your videos. One of those capabilities is to extract the audio as an MP3.

Getting ready

Make sure that you have moviepy installed in your environment:

pip install moviepy

We also need to have ffmpeg installed, which we used in the previous recipe, so...
