In web development, we often encounter web Capture and analysis, various languages can complete this function. I like to use Python, because Python provides a lot of mature modules, it is easy to achieve web crawler. But in the crawl process will encounter coding problems,

that can be freely suspend, execute, and kill at certain times. The program controls the Coroutine as if the operating system controls the process, but at a much lower cost. This is also an important reason why many languages support asynchronous operations in a coroutine way, including Golang, Python, JavaScript (ES6), Erlang, and so on. Talk is cheap, show me your code. Here we use a very simple

Python supports multithreading, mainly through the thread and threading modules. This article mainly shares with you how to implement multi-threaded web crawler in python. For more information, see, there are two ways to use a Thread. One is to create a function to be executed by the Thread, and pass the function into the Thread object for execution. the other is

1. Project background In the Python instant web crawler Project Launch Note We discuss a number: programmers waste too much time on debugging content extraction rules (see), so we launched this project, freeing programmers from cumbersome debugging rules and putting them into higher-end data processing. This project has been a great concern since the introduction of open source, we can be developed on the b
