·Web application development

Python is often used for Web development. As Python’s Web development frameworks gradually mature, such as Django, flask, etc., developers can more easily Develop and manage complex web applications. Through the mod_wsgi module, Apache can run Web programs written in Python. To give the most intuitive example, Google, the world's largest search engine, widely uses the Python language in its network search system. In addition, Douban (shown in Figure 1), which we often visit and integrates movies, reading, and music, is also implemented using Python

. Not only that, the world's largest video website Youtube and Dropbox (a network file synchronization tool) are also developed in Python.

·Automated operation and maintenance

Python is a standard system component, and Python can be run directly under the terminal. There are some Linux distributions whose installers are written in Python, such as Ubuntu's

Ubiquity installer, Red Hat Linux and Fedora's Anaconda installer, and so on. In addition, the Python

standard library contains multiple libraries that can be used to call operating system functions. For example, through the pywin32 package, we can access Windows COM services and other Windows APIs; using IronPython, we can directly call the .Net Framework.

·The field of artificial intelligence

Artificial intelligence is a very popular direction nowadays. Python

In the field of artificial intelligence, machine learning, neural networks, and depth In terms of learning and other aspects, they are all mainstream programming languages. It can be said that artificial intelligence developed based on big data analysis and deep learning is essentially inseparable from the support of Python.

·Web crawler

The Python language has been used to write web crawlers for a long time. Search engine companies such as Google heavily use the Python language to write web crawlers. From a technical level, Python

provides many tools for writing web crawlers, such as urllib, Selenium and BeautifulSoup, etc. It also provides a web crawler framework Scrapy.

·Game development

Many games use C++ to write high-performance modules such as graphics display, and use Python or Lua to write game logic. Compared with Python, Lua’s functions are simpler , the size is also smaller, but Python supports more features and data types. In addition, Python

can directly call Open GL to implement 3D rendering, which is the technical basis for high-performance game engines. In fact, there are many game engines implemented in Python language, such as Pygame, Pyglet

and Cocos 2d, etc.
