This blog is only for my spare time to record articles , Publish to , Only for users to read , If there is any infringement , Please let me know , I'll delete it .
This article is pure and wild , There is no reference to other people's articles or plagiarism . Insist on originality !!

Preface

This is a summary or table of contents , Put me in CSDN All the articles run through , bring Python Reptile beginners Just by the post , You can achieve Python Introduction to reptiles The edge of the threshold .
Yes, of course , It's not enough to sum up my personal experience , You can only tell me the way you have walked , Help you avoid detours .

To be fair , I think it's more conscience + Quality Python Introduction to reptiles course , Highlights are as follows :

  1. post
  2. Multiple cases
  3. Source code
  4. Video Explanation

The quality of the course content can even be said to be more free than the current network, or even a few Training institutions for leek cutting Of Python Introduction to reptiles Still better , You tell me , Who doesn't love ???
( Yes, of course , Other people's tutorials also have a lot to learn from . Because what I'm talking about here is not comprehensive enough , But I'm not in training , Do I have to teach hand in hand ???)

The interesting thing is : My style of writing is no style . So you don't have to care about what you have or don't have , All in all , Content , Very dry , Prepare mineral water , That's right .


The articles are mostly dry goods , Please feel free to eat .

By the way, I can make complaints about it. , Such a good article does not recommend the home page to me , Every time the front page pushes me those things like 《 I'll teach you to climb the Douban movie Top250》 And so on , please , I don't need it, OK !!!
So I really feel , CSDN The home page recommendation system is not generally bad !!!


1. Python An outline of the crawler tutorial

Here are a few steps :

  1. Python Configuration of operating environment ;
  2. Python Common knowledge + Simple crawler case ;
  3. Python Automated crawler ;
  4. The difficulty is gradual Python Reptiles ;
  5. ordinary Js Reverse crawler ;
  6. Data visualization .

After learning , It can be called Python Introduction to reptiles 了 . Maybe it's not a beginner either , It's said that it's more appropriate to get to the edge of the threshold .


2. Python Reptile related

Some of the articles in the outline have been written , The old article may be changed later , Or just take it and use it . Don't dislike .
More is to integrate the old articles . When you are free, you can update your blog posts and videos .
Update speed with fate ,
Cold food , Heat it up and you can eat it .

The following contents are all dry goods , Please bring your own mineral water , Or you can't eat it ;


2.1 Python Configuration of operating environment

It is said that , If a worker wants to do a good job, he must sharpen his tools first , So here's the installation Python, And configure it Operating environment .

Here I recommend novice installation Anaconda, Because it saves a lot of things , For specific operation, click the following link .

I believe that after the configuration of the running environment you , I can't wait to sharpen my knife to pigs and sheep .


2.2 Python Common knowledge + Simple crawler case

This article mainly introduces some commonly used Python grammar , And a few simple ones Python Reptile cases .
Novels 、 picture 、 music 、 Video and other simple cases do an introduction .

thus , You are already a great Python Reptilian Xiaobai 了 .


2.7 I recommend some Python Reptile books

I've read the following books here Python Reptile books , Take a look at :

  • Cui Qingcai's 《Python 3 Web crawler development practice 》
  • Wei Shidong's 《Python 3 Anti crawler principle and bypassing actual combat 》
  • Xie Qiankun's 《Python The crawler development From introduction to practice ( Micro lecture version )》

3. Python Other articles

Here are some interesting but not very practical articles , If there is plenty of time , Take a look at .

4. There will be a follow-up update to supplement

I summarize the above article at present ,
There's a new post , Then I'll add .


5. The latter

Marked as no Of , Update the uncertainty depending on the situation ;
Marked as To be updated Of , It's also a slow update , There should be at least one article a month !!!

I Believe , The whole article follows the words of learning , You will get something .!!!
If you encounter problems in the learning process , Be sure to remember to solve the problem yourself .
