10 recommended articles about python crawling

Recently, I have been studying content related to text mining. The so-called clever woman can’t make a meal without rice. If you want to carry out text analysis, you must first get the text. There are many ways to obtain text, such as downloading ready-made text documents from the Internet, or obtaining data through APIs provided by third parties. But sometimes the data we want cannot be obtained directly because there is no direct download channel or API for us to obtain the data. So what should we do at this time? A better way is to use a web crawler, which is to write a computer program to pretend to be a user to obtain the desired data. Taking advantage of the efficiency of computers, we can obtain data easily and quickly. So how to write a crawler? There are many languages ​​​​that can be used to write crawlers, such as Java, php, python, etc. I personally prefer to use python. Because Python not only has built-in powerful network libraries, but also has many excellent third-party libraries. Others have directly built the wheel, and we can just use it. This brings great convenience to writing crawlers. No exaggeration
