1. What exactly is python?
Python was designed in the early 1990s by Guido van Rossum of the Dutch Society of Mathematics and Computer Science Research. ** Simply put, Pyhton is a programming language! **But it can provide efficient high-level data structure, but also simple and effective object-oriented programming. As a popular programming language, Python has a high popularity, and Python and the current popular artificial intelligence are closely related to this.
2. Why do most people choose to learn Python?
Nowadays, many people who learn programming languages would prefer Python. Why? Because Python is easier to learn than other languages, and it is an introductory language suitable for programming beginners.
There are several reasons for this:
1. Python's syntax is concise and easy to understand
2. Python can be integrated with c/c++ and java for cross-platform development.
3. Python has rich and powerful library support. It also contains class libraries to solve various problems, no matter what functions are implemented, there are ready-made class libraries that can be used.
4. The development efficiency of Python can be significantly improved, and the files of Python code are less than that of C, C++ and Java code.
5. The Python language has a wide range of applications, such as Web development, network programming, automated operation and maintenance, Linux system management, data analysis, scientific computing, artificial intelligence, and machine learning.
But Pyhton also has obvious shortcomings. For example:
1. The execution speed of Python is not fast enough.
2. Python cannot be used for GUI applet development, and the error detection of the code is troublesome.
However, no matter which language is perfect, it has shortcomings, large or small. However, Python has a lot of free materials for learning, and it is a language with low learning costs.
3. What can Python do?
Many people will have these questions, what can you do if you learn Python? In fact, there are many things that Python can do,
such as:
1. Homemade mini games (Tetris, Snake, Tank Battle, etc. are all OK.) You
need these game codes to privately write 01 or deduct 1.
2. Crawlers (crawling data)
Web crawlers (also known as web spiders, web robots, in the FOAF community, more often web chasers), are a type of crawling information on the World Wide Web automatically according to certain rules Program or script. Generally speaking, it is to obtain the data you want on the web page through the program, which is to automatically grab the data. 
3. Operating Word, Excel and other office software
Python has many tool libraries, which can automate office operations such as excel, word, ppt, email, pdf and other office software. For example, merge PDF files, merge Excel in batches, realize Excel pivot tables, and convert Word to PDF in batches.
4. Automatically send and receive mail
SMTP simple mail transfer protocol, which can transmit mail across the network, can realize the mail transmission between the same network processing process, and can also realize the mail transmission between the process and other networks through a relay or gateway. And Python's smtplib module encapsulates SMTP, so you can use Python to easily send emails. 
5. Draw a chart and
create a dynamic page animation through the code, you can show your own technology invisibly. And a rose is the cheapest 20 yuan, and typing a code is not costly! You know everything!
6. Homemade interesting gadgets.
In fact, Python can achieve a lot of automated operations, such as WeChat automatic reply and many people now use it to detect people who have deleted their WeChat. In general, learning Python can do a lot of things, and they are all very simple, and the code is less than other languages!
What positions can I go to when I learn Python?
Generally, our learning is conditional and purposeful. For example, after learning Python, can we bring us good job opportunities? In fact, there is no need to worry about this, because there are actually a lot of positions in Python!
1. Reptiles.
2. Data analyst.
3. Web back-end development engineer
4. Machine learning.
5. Games, images, XML, robots, etc.
In general, the future development of learning Python must not be bad, and the treatment of each position is very good, even if your education is not high, it can also bring you an ideal salary. At the same time, it will bring you more employment directions. So Python is a springboard. After you use it, you can jump very high.
How to learn Python?
Although Pyhton is a relatively simple programming language, it also has a certain degree of difficulty. So when you decide to learn Python from the beginning, you must learn it systematically.
Learning Python can be divided into several steps:
1. Learn to understand basic knowledge.
For example, basic syntax, data types, control structures, functions and classes, file processing, network programming, and concurrent programming.
2. Put the learned knowledge into practical application.
For web development, data analysis, machine learning, etc., you also write code and implement the functions of the written code.
3. Consolidation and understanding of learned knowledge.
Repeated learning and consolidation, you can take on some outsourcing tasks, and consolidate your knowledge and ability while working part-time.
Having said that, everyone should be able to understand PYTHON clearly! I still want to recommend the Python learning group I built myself : 705933274 , all of whom are learning Python. If you want to learn or are learning Python, you are welcome to join. Everyone is a software development party and will share dry goods from time to time ( Or some game source code), including a copy of the latest Python advanced materials and zero-based teaching compiled by myself in 2021. Welcome friends who are in advanced and interested in Python to join!
