Today, I will talk to you about the extent to which Python needs to learn before you can write about crawlers. Many people may not know much about it. In order to make you understand better, the editor summed up the following content for you. I hope you can get something according to this article.

To what extent does Python learn to write about crawlers? Many friends are very interested in Python crawler. We can write Python crawler when we learn Python technology development. Let's discuss it together.

Python crawler

If you want to be proficient in using Python crawler, then some basic knowledge of Python must be understood, such simple knowledge as installation and use of Python environment, Python basic syntax, list, dictionary, and string handling all need to be learned.

Secondly, the main library used by Python crawlers is the request library, which you have to learn, and the data you get need to be processed by yourself, through data filtering rules, regular expressions and other technologies. If it is a dynamic website, A Xiu should learn selenium.

Of course, you also need to learn some front-end basic knowledge, because the data you crawl is on the network, so you must understand the front-end basic, otherwise you may not be able to find the data you need, so how to crawl data.

In addition, many websites nowadays have developed their own anti-climbing mechanism, so some common anti-climbing measures are also something you need to learn, and you will not be able to crawl the data you want without learning.

To sum up here, if you want to write a Python crawler yourself, you must learn the basics of Python, including environment installation, basic syntax, dictionaries, regular matching, and some data processing techniques. The second is the library request that simulates the request, as well as some anti-crawling techniques and front-end foundations.

Does it feel like you have to learn a lot after reading it? if you want to develop and use Python crawler smoothly, you need to master these.

After reading the above, do you have any further understanding of how much Python needs to learn before you can write about crawlers? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
