It is said that reptiles crawl well, and you can eat all you can!
Although there are many jokes like this, there are still many people interested in Python crawlers. Once you enter the reptile, it is as deep as the sea, and the further you go, the deeper you sink, the kind that falls into a pit and cannot climb out.
Why are there so many people who want to learn Python crawlers? Part of the reason is that Python crawlers are cool and can crawl something they want. Another part of the reason is the Python crawler, which can easily help collect some data and assist in the work. And you can also work part-time as a side job. So many people's interest in Python crawlers never stops.
Many beginners are very interested in Python reptiles, but they are still at a loss when learning, and they don't know where to start. The theory is solid, but it can be broken in practice.
Here I recommend a 521-page "Python Web Crawler Actual Combat" 2nd Edition published by Tsinghua University. Starting from actual combat, different crawlers are selected according to different needs, and several Python web crawlers are explained in a targeted manner.
A total of 10 chapters, rich in content, typical examples, strong practicability. It is suitable for beginners of Python web crawlers, beginners of Python data analysis and mining technology, as well as teachers and students of related majors in colleges and universities and training schools.
