What are the applications of python in actual work
Whether it is work or life, Python is a practical and interesting skill.
Python has a wide range of application fields, which can be summarized in the following figure:
Applied to: Python development, Python crawlers, big data;
In terms of life, reptiles have added a lot of fun to our lives and made our daily lives more convenient.

Python Development
Automated testing, automated operation and maintenance, WEB development ( Website development) and artificial intelligence all belong to Python development.
Automated testing - write simple implementation scripts in Python and use them in Selenium/lr to achieve automation.
Automated operation and maintenance - Python is very important for server operation and maintenance.
Currently, almost all Linux distributions come with a Python interpreter to use Python scripts for batch file deployment and operation adjustment~
And Python provides a full range of With Fangfang's tool collection, combined with the Web, it will become very simple to develop tools that facilitate operation and maintenance.
WEB development - Python's most popular WEB development framework Django is very popular in the industry, and its design philosophy is also commonly used in other programming language design frameworks~
If it is a website End, using it for a single website, the backend service is easier to maintain. As we often see: Gmail, Zhihu, Douban, etc.~
Artificial intelligence is a very popular direction now. Most of the several very influential AI frameworks released now are Implemented in Python.
Python crawler
In the current era of information explosion, a large amount of information is displayed through the Web. In order to obtain this data, web crawler engineers came into being.
But this is not only our daily simple data capture and analysis, it can also break through the common anti-crawler mechanisms of ordinary websites, as well as write deeper crawler collection algorithms.
You can also search the Internet for interesting things that others have done through crawlers. Let me pick a few to talk about:
Python Big Data"The first program written in Python was Crawl the pictures on the Encyclopedia of Embarrassing Things, automatically download them locally, and automatically divide them into folders and save them. At that time, I thought, Oops, it’s so NB~”
”12306 train ticket query tool, Ctrip air ticket query; crawling User reviews of Meituan Movies and Douban Movies; a simple Meituan restaurant crawler and creating a simple heat map based on geographical coordinates...these are not difficult.” And the crawled data was analyzed and visualized using Excel and Python (matplotlib) respectively..."
"I tried to crawl the product information of JD.com's hot sales and Taobao's rush sales (or Juhuasuan), but it didn't work. It's quite simple when I think of it, mainly because I haven't taken any anti-crawler measures..."
Data is the core asset of a company. Extracting valuable information or patterns from messy data has become the primary task of data analysts.
Python's tool chain provides extremely efficient support for this heavy work. Data analysis is based on crawlers. We can easily crawl down massive amounts of data to perform analysis.

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
