This is the month （2022 year 05 month ） The latest ranking of programming languages ,Python take the first place at the triennial palace examination , I remember last year, it seemed 5 Before month ,Python He has been ranked the second in the millennium , Later, he rose to the throne of the dragon head , It hasn't changed .
This article focuses on sharing about Python Some ideas about the learning path , Welcome to exchange .
Today I collected some articles about sharing learning paths , Many of them are full of contents , In fact, no matter what you want to learn , Both
then ： Think about your goals ？ Web Development ？ Data analysis ？ Artificial intelligence （AI）？...
continue ： Think about how I learn ？
Last ： Continuously improve yourself Learning path Learning style Communication way Knowledge system wait
Only in this way can you become a great God （ Great gods are rare after all , It is not difficult to be a senior engineer ）.
Think first ： Don't follow suit , Others say good is good , Investigate yourself first 、 analysis 、 Or ask experienced seniors .
When you want to learn Python when , Suggest Baidu first , From these three aspects, we can get a general understanding of .
Python Application scenarios of ： Share later , Wait quietly for a while
Python It is very hot in China There is a chart picture at the head of the article , Don't be confused by this ranking list , This ranking is not aimed at the domestic situation . About Tiobe Baidu Encyclopedia describes it like this
TIOBE Ranking List [1] It's based on experienced programmers on the Internet 、 Number of courses and third-party vendors , And use search engines （ Such as Google、Bing、Yahoo!） as well as Wikipedia、Amazon、YouTube and Baidu（ Baidu ） Count the ranking data , Just to reflect the popularity of a programming language , It doesn't say whether a programming language is good or not , Or how much code a language writes .
for example ： In the first 10 Bit PHP, The ranking is relatively high , But now it is not very fragrant in China , At first, the websites or systems of many large domestic factories used PHP Development , Later, they all changed to Java、Go Refactored . How to know the degree of heat ： You can search on the recruitment website ,1: Look at the number of job openings 2: Job requirements 3: Position salary
go back to Python topic of conversation , It's still hot , Especially in the field of data analysis , The perfect programming language , So if you want to do data analysis in the future 、AI Aspect , Study Python, At least in the short term , There will be no problem in the direction .
Tips ： Search more about the past of programming languages 、 Now? 、 Future trends , Don't follow suit , Others say it's good to learn this , Just drive me , No investigation, no voice
I'm divided into 2 Pictures , A picture text is too small , Orientation is a crucial link , If the direction is not clear , You can learn everything you want , It is possible to learn from a bottle less than half a bottle .
Next , The picture is a bit misplaced
From the general direction , Can be divided into
Server side development
Scientific Computing
Data analysis
machine learning / Deep learning
automated testing / Operation and maintenance
… These directions , Let's not say that each one is too good , It's not easy to make a decent job . For example, deep learning , And natural language 、 Image vision, etc . Each sub branch goes deep into , Enough to learn for several years .
Some directions will depend on peripheral technologies , Then it can become a system , For example, server-side development
You probably need such a learning path
Python Based on learning
Learning framework ：Flask Or Django
Study SQL Basic grammar （DML、DDL）
Study MySQL（ relational database ）
Study Redis（ Cache database ）
Python Advanced knowledge learning such as concurrent database
Message queues may then be involved 、 Document database and so on If you're a rookie , Looking for a back-end development job , Learning these , It will be faster to join the team , Can quickly find the feeling .
If you are in College , It is suggested that you can consider following this path Scientific computing library learning data analysis related several libraries machine learning depth learning
Why should I suggest this First of all ： Data analysis 、AI It is a popular position , The demand for talents is very strong , Second, employment is easy ： High starting salary , Make money third ： machine learning 、 Deep learning deep learning will involve a lot of mathematical knowledge , For example, statistics 、 Probability, etc , The students are learning mathematics , Can well understand the derivation process of the model . For seniors who have graduated for several years , It is very likely that all the mathematics learned in the University have been returned to the teachers , Want to learn AI We need to learn something new , So the students who are studying in University have advantages
About the learning path Welcome to discuss with you , Sharing experience
About the environment , Since learning Python
Next choose IDE, It is recommended that these two models be installed by everyone Pycharm Or VSCode： Suitable for projects Web Website development backend development JupyterLab： The tool of choice for data scientists Learning data analysis 、 machine learning 、 Deep learning must be installed with learning operation and maintenance , automated testing , There is no need to install this tool
Editor ：Sublime Text Or Atom Lighter editor , It is recommended to install
About installation , I was in the official account 【 The little coder and the old coder 】 I have written some articles in , You can refer to it install Python That thing , The most detailed tutorial Ten thousand words long text ： Have a deep and comprehensive understanding of Conda All kinds of operation Data science artifact JupyterLab Use ( Lite version )
First map
Novice tutorial : Take data analysis for example , This website provides many basic tutorials Python 3 course Pandas course NumPy course Matplotlib course
A good book ： Why is it called a good book , I want to remind you not to buy a pile of books , First, you can't see it , Second, books are also very expensive , Third, many of the contents are identical for example Python Based on learning , Just buy a python book machine learning , You can buy a book by teacher zhouzhihua Suggest ： immediately 618 了 , You can take this opportunity to stock up on books
I don't say much nonsense , Upper figure
About Yongjin stage , Ten million
Don't feel like you've read a few books , Wrote a little bit of code , The level is high
Don't think ... This is to pour cold water on everyone , Before you see the real God , Always be humble , Study , Study , I'm learning
I want to learn some advanced ways
Looking for projects to do For example, you learned the knowledge of machine learning , You can go to the competition , Verify what you have learned, such as data analysis , You can download a copy of fund data , Then analyze the data from multiple perspectives
github github Many excellent framework source code and project code are open source on , You can find one that suits you , To learn other people's code 、 thought 、 Ideas, etc
Open source framework It is suggested that energetic students can study the source code of the open source framework , Improve your understanding of the bottom layer and your ability of architecture design
gitee That's not enough , Managed a lot of source code , and github similar
Upper figure
About playing games , Now many competitions are team competitions , In the process of participating in the competition , You can train yourself in many ways .
such as ： Planning capacity 、 The coordinated ability 、 leadership 、 External social skills 、 Technological upgrading power .
The coder took part in last year ：“ tianchi ·TEENTOP A cup of ”AI Junior challenge - Data science challenge intermediate track , Won the championship , Although the result is good , But this is not the most important , It is important to
Made a few like-minded friends who like to learn programming , Learning together ;
Once you enter the ape gate, it is as deep as the sea , Since then, I have become OI people .
because 2 The causes of the epidemic in Beijing in January , Later, I didn't go to Hangzhou Ali Da Mo academy to participate in the finals , Although I'm sorry , If I go to , Can broaden your horizons , Recognize your own shortcomings , See the bigger world outside
You may have some doubts , How can these two things be powerful weapons , Bullshit .
It's not bullshit , The purpose of installing these two artifacts
Gradually improve your knowledge system
Improve your learning efficiency The following picture shows the coder learning OI Organize the knowledge system on a daily basis
Don't let your knowledge be too fragmented , Develop the habit of taking notes 、 Sort out knowledge habits
About the learning path , Welcome to communicate with you , To discuss , Focus on ： The little coder and the old coder , Continue to share high-quality knowledge together
