Recently, many people have said that they are just starting to learn, and what free learning websites are there for self-study. So, I took advantage of the free time to sort out the major websites, and found 5 better learning websites, and they are all free , which are more suitable for beginners to understand some basic grammar and solve BUG problems.
1. Python official Chinese website
Website address: https://docs.python.org/zh-cn/3/
The official website not only has basic grammar references, Python standard module introductions, but also related tutorials. It is more convenient to check interface documents and so on.
2、w3school
Website address: http://www.w3school.com.cn/
This is an old website. I remember that when I first started learning programming, I often searched for the application of Html tags on it. However, there are also Python applications on it. I forgot how to use some built-in functions. It is quite nice to check it out.
3. Rookie Tutorial
Website address: http://www.runoob.com/
This is also good, as long as you are a novice to learn all kinds of programming languages above, including the installation and use of the database, the operation steps will be listed step by step. I believe that novice friends will definitely like this website very much when they see it. Just search for any information you want.
4、python Code Example
Website address: https://www.programcreek.com/python/
This is an English website, and you can use this website with some English skills. It mainly collects a large number of usage examples of python modules, and searches for relevant examples by searching the module name for reference.
For example: you can search how datetime is used, you can search...
You can directly locate how a certain function in it is used, and just follow the instructions after searching.
5、LearnPython
Website address: https://www.learnpython.org/
This website is also an English website, which contains some elementary and advanced usages, and you can try it if you need it.
Finally, I would like to thank everyone who has read my article carefully. Reciprocity is always necessary. Although it is not a very valuable thing, you can take it away if you need it:
1. Introduction to Python
The following content is the basic knowledge necessary for all application directions of Python. If you want to do crawlers, data analysis or artificial intelligence, you must learn them first. Anything tall is built on primitive foundations. With a solid foundation, the road ahead will be more stable.All materials are free at the end of the article！！！
Include:
Computer Basics
python basics
Python introductory video 600 episodes:
Watching the zero-based learning video is the fastest and most effective way to learn. Following the teacher's ideas in the video, it is still very easy to get started from the basics to the in-depth.
2. Python crawler
As a popular direction, reptiles are a good choice whether it is a part-time job or as an auxiliary skill to improve work efficiency.
Relevant content can be collected through crawler technology, analyzed and deleted to get the information we really need.
This information collection, analysis and integration work can be applied in a wide range of fields. Whether it is life services, travel, financial investment, product market demand of various manufacturing industries, etc., crawler technology can be used to obtain more accurate and effective information. use.

3. Data analysis
According to the report "Digital Transformation of China's Economy: Talents and Employment" released by the School of Economics and Management of Tsinghua University, the gap in data analysis talents is expected to reach 2.3 million in 2025.
With such a big talent gap, data analysis is like a vast blue ocean! A starting salary of 10K is really commonplace.
4. Database and ETL data warehouse
Enterprises need to regularly transfer cold data from the business database and store it in a warehouse dedicated to storing historical data. Each department can provide unified data services based on its own business characteristics. This warehouse is a data warehouse.
The traditional data warehouse integration processing architecture is ETL, using the capabilities of the ETL platform, E = extract data from the source database, L = clean the data (data that does not conform to the rules), transform (different dimension and different granularity of the table according to business needs) calculation of different business rules), T = load the processed tables to the data warehouse incrementally, in full, and at different times.
5. Machine Learning
Machine learning is to learn part of the computer data, and then predict and judge other data.
At its core, machine learning is "using algorithms to parse data, learn from it, and then make decisions or predictions about new data." That is to say, a computer uses the obtained data to obtain a certain model, and then uses this model to make predictions. This process is somewhat similar to the human learning process. For example, people can predict new problems after obtaining certain experience.

6. Advanced Python
From basic grammatical content, to a lot of in-depth advanced knowledge points, to understand programming language design, after learning here, you basically understand all the knowledge points from python entry to advanced.
At this point, you can basically meet the employment requirements of the company. If you still don’t know where to find interview materials and resume templates, I have also compiled a copy for you. It can really be said to be a systematic learning route for nanny and .
But learning programming is not achieved overnight, but requires long-term persistence and training. In organizing this learning route, I hope to make progress together with everyone, and I can review some technical points myself. Whether you are a novice in programming or an experienced programmer who needs to be advanced, I believe that everyone can gain something from it.
