Which is the best Python training choice ? For many years, Python has been ranked among the most popular programming languages. It can be applied to almost any development, and it aims to improve the development efficiency of programmers rather than the code they write. This is why more and more people choose to use Python!
What do I need to know to participate in Python training ? Today I will explain to you: how to learn reptiles !
As a zero-based Xiaobai, it can be roughly divided into three stages to achieve. The first stage is to get started and master the necessary basic knowledge, such as Python basics, the basic principles of network requests, etc. The second stage is to imitate and follow others ’crawlers Coding, understand each line of code, familiar with mainstream crawler tools, the third stage is to do it yourself, at this stage you start to have your own problem-solving ideas, you can independently design a crawler system.
The technology involved in crawlers includes but is not limited to proficiency in a programming language ( here Python is used as an example ) HTML knowledge, basic knowledge of HTTP protocol, regular expressions, database knowledge, the use of commonly used packet capture tools, the use of crawler frameworks, involves Large-scale crawlers also need to understand distributed concepts, message queues, commonly used data structures and algorithms, caches, and even machine learning applications. Large-scale systems are supported by many technologies. Data analysis, mining, and even machine learning are inseparable from data, and data often needs to be obtained through crawlers. Therefore, even if the crawler is learned as a major, there is great promise.
So do you have to complete the above knowledge before you can start writing reptiles ? Of course not, learning is a matter of a lifetime, as long as you can write Python code, you can get started with reptiles directly, like learning to drive a car, as long as you can start driving , Writing code is much safer than driving.
What do you need to master Python training ? First of all, you need to understand what Python is used: Python is suitable for website, desktop application development, automated scripts, complex computing systems, scientific computing, life support management systems, Internet of Things, games, robots, natural language processing, etc. in many ways. Moreover, even for those who have never had development experience, Python code is concise and easy to understand. Because the Python program code is simple, compared with other programming languages, later program maintenance is easier and more comfortable. From a business point of view, the required cost is reduced and the programmer's efficiency is improved !
