What are the characteristics of Python programming language?

1. Easy to learn, clear and elegant, and fast in development.

① Easy to learn: Compared with C and Java, python's learning cost and difficulty curve are much lower, which is more suitable for beginners and is a bottom-up technical climbing route.

② Clarity and elegance: python's syntax is very concise, the code amount is very small, it is very easy to write, and the code testing, refactoring and maintenance are very easy. A small script may need 1000 lines of code in C, hundreds lines in Java, but only a few dozen lines in python.

③ Fast development speed: As far as development speed is concerned, python's development speed is the second and no one dares to call it the first, which is well known.

2. Cross-platform, portable, extensible, interpretive and object-oriented dynamic language.

① Cross-platform: python fully supports mainstream operating systems such as Windows, Linux and MAC. The so-called cross-platform refers to developing and running programs with different operating systems without modifying the code.

② Portability: The code can be ported to other platforms without much change.

③ Extensibility: python itself is written in C language, and you can completely embed C in python, thus improving the running speed and efficiency of the code. You can also rewrite any module of python in C language, and fundamentally rewrite python.

④ Explanatory type: python language is analyzed line by line by the interpreter during execution, runs line by line and outputs the results.

⑤ Object-oriented: python language has all the features and functions of object-oriented and supports class-based program development.

3. Built-in battery, a large number of standard libraries and third-party libraries

Python provides us with a very perfect basic library, covering systems, networks, files, GUI, databases, text processing and other aspects. By default, they are installed with the interpreter, and all platforms are common. You can do most of the work without installing third-party support. This feature is vividly called the built-in battery.

4. Active community, many contributors and mutual assistance.

The technical community can provide us with great help in language learning and use. No matter before or after the study, as long as there are problems, Daniel in the technical field can help us solve them. With these help, we can better understand, learn and use the language. At the same time, the technical community also promotes the development direction and functional requirements of python language, prompting companies to use python language more and recruit python programmers.

5. Open source language has a great development momentum.

Python is written in C language and uses GPL open source protocol. You can get its source code for free, and learn, study and even improve it. Many people gather firewood, and more people participate in the development of python, promoting its better development and more applications, forming a virtuous circle. Why python is becoming more and more popular is because of its openness and freedom, gathering popularity and forming a community. Many people contributed and more and more people used it, which naturally increased the market share. Enterprises, companies and manufacturers have to use python to provide more and more python programmers. This is the power of open source.
