What can python do? What is it?

Python is a widely used interpreted, high-level programming, general-purpose programming language created by Guido van Rossum. The first version was released in 1991. It can be regarded as an improved LISP. Python's design philosophy emphasizes code readability and concise syntax. Python allows developers to express ideas in less code than C or Java. Whether it is a small or large program, the language attempts to make the structure of the program clear and unambiguous.

Python can do:

Web application development

Before it became well-known for big data and artificial intelligence, Python It has been widely used in the field of web development, producing web development frameworks such as Django, Flask, and Tornado. Thanks to its concise syntax and dynamic language features, Python has high development efficiency and is therefore favored by entrepreneurial teams.

Some well-known Internet companies/products that use Python as their main development language:

豆瓣
知乎
果壳网
Instagram
Quora
Dropbox
Reddit

Due to the versatility of the backend server, in addition to narrowly defined websites, the same goes for the server sides of many apps and games. Implemented in Python.

Automated Operation and Maintenance

In the field of web development, Python is just one of many language choices; but in the field of automated operation and maintenance, Python is a necessary skill. Flexible functions and rich class libraries make it the preferred language for operation and maintenance engineers. A large number of automated operation and maintenance tools and platforms are either developed in Python or provide Python configuration interfaces. Just from the fact that Linux has built-in Python, it also shows its status in the server and operation and maintenance fields.

Therefore, although many companies do not use Python for their core business, they also use it extensively in management systems, operation and maintenance, etc. For example, Facebook engineers maintain thousands of Python projects, including infrastructure management, advertising API, etc.

Web Crawler

Also called web spider, it refers to a program script that collects data from the Internet. For many data-related companies, crawler and anti-crawler technologies are important guarantees for their survival. Although crawlers can be written in many languages, the flexible Python is undoubtedly the current first choice. The Python-based crawler framework Scrapy is also very popular.

The largest "crawler" company on the planet--Google has always promoted Python. It not only uses Python extensively within the company, but also makes great contributions to the development community. Even Guido van Rossum, the father of Python, worked at Google for seven years.

Data Analysis

After obtaining massive data through crawlers, the data needs to be cleaned, deduplicated, stored, displayed, and analyzed. In this regard, Python has many Excellent class libraries: NumPy, Pandas, and Matplotlib can make your data analysis work more efficient.

Scientific Computing

Although Matlab has an irreplaceable position in the field of scientific computing, Python, as a general programming language, can bring a wider range of applications and Richer class library. Class libraries such as NumPy, SciPy, BioPython, and SunPy play an important role in biological information, geographic information, mathematics, physics, chemistry, architecture and other fields.

The famous NASA has already used Python as its main development language.

Artificial Intelligence

Python is a mainstream programming language in data mining, machine learning, neural networks, deep learning, etc. in the large field of artificial intelligence. It has gained Extensive support and applications.

Machine learning: Scikit-learn

Natural language processing: NLTK

Deep learning: Keras, Google's TensorFlow, Facebook's PyTorch, Amazon's MxNet

These tools that have become mainstream in the industry are either developed in Python or also provide Python versions. Python has undoubtedly become a must-have language in the field of AI.
