The March Tiobe programming language rankings are coming as scheduled. What are the new highlights this month? Programmers, let's take a look:
Top 20 Tiobe Programming Leaderboard

In this ranking, the top three are still Python, C language, and Java, especially Python, which has a strong performance, and its share has increased by 3.95%, far exceeding other programming languages!
Not surprisingly, Python will continue to "occupy" the top position in the next period of time. The main reason for this result is inseparable from the advantages of the Python programming language.
01 Features of the Python language
As a relatively "new" programming language, Python language can stand out among many programming languages, and keep pace with "veteran" programming languages such as C language, C++, Java, etc., which undoubtedly shows that it has many advantages of high-level languages. Unique, with its own characteristics. Below we will briefly explain the advantages of the Python language .
(1) Concise. When implementing the same function, the number of lines of Python code is often only 1/5~1/3 of the number of C, C++, and Java codes.
(2) The grammar is beautiful. The Phon language is a high-level language, and its code is close to human language. As long as you master the mnemonic represented by English words, you can roughly understand the Python code; in addition, Python reflects the logical relationship between statements through forced indentation. Anyone who writes Python The codes are standardized and have a unified style, which increases the readability of the Python code.
(3) Easy to learn. Compared with other programming languages, Python is an easy-to-learn programming language, which makes programmers pay more attention to solving problems rather than the syntax and structure of the language itself. Most of the Python syntax is derived from the C language, but it abandons the complicated pointers in the C language, and at the same time adheres to the principle of "using the best solution to solve the problem", which simplifies the syntax and reduces the difficulty of learning.
(4) Open source. Python itself has enough compelling advantages that attract a large number of people to use and study Python; Python is one of FLOSS (free/open source software), users can freely download, copy, read, modify code, and The ability to freely distribute modified code has made a considerable number of users enthusiastic about improving and optimizing Python.
(5) Portable. As an interpreted language, Python can be executed on any platform with a Python interpreter installed, so Python has good portability, and programs written in Python can run on any platform without modification.
(6) Good scalability . Python can import .py files from a high level, including Python standard library files, or .py files written by programmers themselves; at the bottom, it can be called by other high-level languages (such as C language, C++, Java, etc.) ) written code.
(7) Rich class library. The Python interpreter has a wealth of built-in classes and function libraries. Programmers from all over the world have contributed hundreds of thousands of third-party function libraries covering almost every application field through the open source community, enabling developers to use function libraries to implement some complex functions. Function.
(8) Universal and flexible. Python is a general-purpose programming language that can be used in various fields such as scientific computing, data processing, game development, artificial intelligence, and machine learning. The Python language is between the scripting language and the system language. Developers can use Python as a scripting language to write scripts or as a system language to write services according to their needs.
(9) There are various modes. The Python interpreter is internally implemented in an object-oriented mode, but at the grammatical level, it supports both object-oriented programming. It also supports process-oriented programming, which can be flexibly selected by users.
(10) Good Chinese support. The Python 3.x interpreter uses UTF-8 encoding to express all character information. This encoding not only supports English, but also supports Chinese, Korean, French and other languages, making the processing of characters by Python programs more flexible and concise.
Python is widely used because of its many advantages, but the shortcomings of Python cannot be ignored. Python mainly has the following disadvantages.
(1) The execution efficiency is not high enough, and the efficiency of the Python program is only 1/10 of that of the C language program.
(2) Python 3.x and Python 2.x are not compatible.
All in all, Python's flaws are not hidden. For programming language beginners, it is easy to learn and is a good choice for contacting the programming field; for program developers, it is versatile, flexible, concise and efficient, and it is a powerful and versatile excellent language.
02 Python is widely used
Python has the advantages of being easy to learn, rich class library, versatile and flexible, and good scalability, and is often used in the following fields.
(1) Web development. Python is the mainstream language for Web development. Compared with widely used languages such as JS and PHP, Python has a rich class library and is easy to use. It can provide multiple solutions for one requirement; in addition, Python supports the latest XML technology and has powerful data Processing power, so Python has a place in web development. The frameworks provided by Python for the field of web development include Django, Flask, Tormado, web2py, etc.
(2) Scientific computing. Python provides the module numpy that supports multi-dimensional array operations and matrix operations, the module Scipy that supports advanced scientific computing, and the module matplotlib that supports 2D drawing functions. It is also simple and easy, so it is used by scientists to write scientific computing programs.
(3) Game development. Many game developers first use Python or Lua to write the logic code of the game, and use C++ to write modules with high performance requirements such as graphics display. The Python standard library provides the pygame module, which can be used to make 2D games.
(4) Automated operation and maintenance. Python is also a scripting language, and the Python standard library provides some libraries that can call system functions. Therefore, Python is often used to write script programs to control the system and realize automatic operation and maintenance.
(5) Multimedia applications. Python provides modules such as PIL, Piddle, and ReportLab, which can process images, sounds, videos, animations, etc., and dynamically generate statistical analysis charts; Python's PyOpenGL module encapsulates the OpenGL application programming interface, providing two-dimensional and three-dimensional Image processing functions.
(6) Reptile development. The crawler program crawls network data in a targeted manner through automated programs to extract available resources. Python has good network support, a relatively complete data analysis and data processing library, and is flexible and concise, so it is widely used in the field of reptiles.
