If you want to use Python as a crawler, but you still don't know Python, these basics are essential. Many friends, especially students at school, feel this amazing when they come into contact with crawlers. I want to learn it. But I don't know where to start. I am confused and learn a lot. Let's take a look at what I need to learn when I want to use python for crawlers!

Getting started with Python

1. Basic knowledge, data types, and process control.

Life is short, and Python is easy to use

2. Functions

Life is short, just use Python

3. Modules

4. I/O Basics

Life is not short, but Python is also used

5. Linux Basics

Linux Basics

Finally, you need to know more about package management and virtual environments. What about these basics!

Web Front-end

Of course, the basics of optics are far from enough. We need to go deep into crawlers. First, we need to understand how this is done and how it works, so the web Front-end learning is essential. Let's take a look at it.

1. Labels

Tag

2. Style

Style

3. JS syntax

4. jQuery

JQuery

5. Ajax

6. bootstrap

The front-end part does not need to be too deep, but it is enough to learn crawlers. As the saying goes, "to do a good job, you must first sharpen the tool." So after learning the following Python knowledge, you can learn crawlers without any worries.

Python advanced

1. Object-oriented

2. decorator and inertia

3. Advanced Module

4. Concurrent Programming (multithreading and multi-process)

What are processes and threads?

Multi-Process

Multithreading

Future Implementation of multi-process and multi-thread

5. Concurrent Programming (coroutine and asynchronous IO)

Coroutine, asynchronous IO

Well, after all these things are learned, you can start official crawler learning. Many things will be easy to understand as soon as you see them, and you will not be able to understand what you want.

Crawler Basics

To learn about crawlers, we must first understand what crawlers are and how they work. Only by knowing ourselves and ourselves can we win a hundred battles. Of course, we all know this. Let's take a look at the basic crawler knowledge.

1. Request and response

2. crawler and anti-Crawler

3. Development Tools

4. Detailed use of the Urllib library and project practices

5. Installation and Use of the requests library and Project Practice

6. Too many pictures

Last crawler bullet

Well, if you just want to get into the door, these are almost the same, but I think every crawler partner wants to become a great crawler to attack the city lion! Let's continue to look at advanced learning methods.
