Can python crawler be self-taught?

Whether it is crawlers that everyone from entry-level players to professional players are doing, or web program development, desktop program development, or scientific computing, image processing, Python programming can be competent. Perhaps because of this attribute, many friends around me have begun to learn Python.

# Can Python crawler teach itself? (Recommended learning: Python video tutorial)

Yes, nothing is difficult in the world, only those who are willing can do it. As long as you make up your mind, thoroughly read the following books, and practice it, I believe your crawler technology will be OK.

Python is a language that represents simplicity. Reading a good Python program feels like reading English. It allows you to focus on solving problems rather than figuring out the language itself.

Python is extremely easy to use because Python has extremely simple documentation

1. If you use Python3 to write crawlers, I strongly recommend the book "Python Network Data Collection", which should be the most popular one at present. The most complete book introducing Python crawlers. You can go to Turing Community to buy the electronic version.

The content of the book is very new and systematic, from beautifulSoup, requests to ajax, image recognition, and unit testing. It is much better than the scattered tutorials on most blogs. After reading the book, you can do some practical projects. At this time, you can go to github to find similar projects for reference.

2. There is also a good book about crawlers in China, "Write Your Own Web Crawler". In addition to introducing the basic principles of crawlers, this book includes priorities, breadth-first search, and distributed crawlers. Multi-threading, cloud computing, and data mining content. It's just implemented in java, but the idea is the same.

It is good to learn Python crawlers through the system, but it is simpler and more crude to write a project directly! (However, at my current level, the codes I write are all streamlined and process-oriented, and the repetitive parts of the code are too much. Many, I am going back to learn object-oriented programming and learn the use of classes and methods. However, I still firmly believe that when getting started, you should practice a project directly and roughly.

3. Search wherever you don’t know! Wherever you report an error, you can correct it! Believe me, 99% of the problems you encounter can be found on the Internet. All you need to do is write code! Search for problems! Fix bugs! You can’t find solutions. In 80% of the cases, your search posture is wrong, and the other 20% may require you to use your brain and change your mind.

Currently in the IT industry, technology is in the new In the ever-changing updates, generations are constantly upgrading, especially in the Python industry. And we know that the professional knowledge learned in school may be difficult to meet the needs of today's society.

Having said so much, if The current situation is not suitable for you to study by yourself. Maybe you don’t have enough self-control. Maybe you don’t have enough time to study by yourself. Maybe you need more professional courses. I believe that professional courses can bring you more things. I believe You will gain more friendships and network resources.
