Here are 10 super useful Python crawler projects that will make it easy to get started without any stress, even if you're a zero-base beginner.
First of all, these programs are completely do-it-yourself. After learning about it, you'll have the ability to crawl data on your own, which is a very powerful skill in today's data-driven age.
Project 1, Simple Web Page Data Crawling. It's like a knockout for crawlers to get started, teaching you how to extract the required information from the most basic web pages, such as the title of an article on a news site, the time it was published, and so on.
Project two, dealing with anti-crawler mechanisms. This is a crawler process often encountered challenges, this project will teach you common anti-crawler means, like IP restrictions, CAPTCHA identification, and give ways to deal with it.
Project three, multi-threaded crawler. When you need to process a large amount of data, multi-threading is like installing a gas pedal for the crawler. This project will introduce the principles and practical methods of multi-threading in Python crawler in detail.
Project 4, Crawling Dynamic Web Pages. Many websites today use dynamically loaded data, and this project will show you how to successfully fetch data on such pages.
Project 5, Data Storage and Management. The crawled data needs to be stored properly, this project involves how to store the data into a database, and the management and analysis of the data.
Project six, API-based crawler. Some websites provide an API interface through which data can be accessed more easily, and this project focuses on this aspect.
Project 7, simulate login crawler. This project teaches you how to simulate login for websites that require login to view all the data, like some forums, social networking sites and so on.
Project 8, Data Cleaning and Preprocessing. Data from web pages can be messy, this project teaches you how to clean and preprocess it for subsequent analysis and use.
Project Nine, Distributed Crawler. When faced with massive amounts of data, distributed crawlers are like a feast of big data, and this project will show you how to build distributed crawlers.
Project 10, timed task crawler. If you need to get data on a regular basis, timed task crawler comes in handy, this project is about how to set up at a specific time to automatically execute the crawler task.
The program also comes with source code courseware, which is like having a personal tutor for you, making you more comfortable with the learning process and understanding the principles behind each step to really master the Python crawler technology.
