What kind of language is python? Why learn python

Now, there are almost more than 600 programming languages ​​​​in the world, but there are only about 20 popular programming languages. If you've heard of the TIOBE rankings, you can get an idea of ​​the approximate popularity of programming languages. The picture below shows the changes in the 10 most commonly used programming languages ​​in the past 10 years:

The commonly used programming languages ​​all have their own strengths and weaknesses, and each has its own advantages.

The Python discussed in today’s article isa high-level combination ofinterpretability, compilation, interactivityandobject-oriented##Scripting language.

Python is designed to be highly readable. Compared with other languages, it often uses English keywords and some punctuation marks in other languages. It has a more distinctive grammatical structure than other languages.

So what kind of

language is the so-called python? First of all, the first point: python is an interpreted language.

This means that there is no compilation link in the development process, which can save a lot of time and energy.

Second point: Python is an interactive language.

This means that you can directly interactively execute the program you write in a Python prompt.

The third point: Python is an object-oriented language.

This means that Python supports object-oriented style or programming techniques in which code is encapsulated in objects.

The fourth point: Python is a language for beginners.

Python is a great language for junior programmers. It supports a wide range of application development, from simple word processing to WWW browsers to games. Python can do a lot for you. Unexpected things.

The above explains what kind of language python is, so let’s learn about this magical language:

Features

of python

. 1. Easy to learn: Python has relatively few keywords, a simple structure, and a well-defined syntax, making it easier to learn. 2. Easy to read: Python code is defined more clearly than other codes.

3. Easy to maintain: The success of Python is that its source code is quite easy to maintain.

4. An extensive standard library: One of Python’s biggest advantages is its rich library, which is cross-platform and compatible with UNIX, Windows and Macintosh.

5. Interactive mode: Interactive mode support, you can enter the language to execute the code from the terminal and get the results, interactive testing and debugging code snippets.

6. Portable: Based on its open source nature, Python has been ported (that is, made to work) to many platforms.

7. Extensible: If you need a critical piece of code that runs very fast, or want to write some algorithms that you don’t want to open up, you can use C or C to complete that part of the program, and then start it from your Python called in the program.

8. Database: Python provides interfaces to all major commercial databases.

9.GUI programming: Python supports GUIs that can be created and ported to many system calls.

10. Embeddable: You can embed Python into a C/C program, allowing users of your program to gain "scripting" capabilities.

In short, Python's positioning is "elegant", "clear", and "simple", so Python programs always look simple and easy to understand. Beginners learning Python will not only get started easily, but also can write in depth in the future. Those are very, very complex programs.

The philosophy of Python is simplicity and elegance. Try to write code that is easy to understand and write as little code as possible.

Above we explained what kind of language python is and introduced the characteristics of this language. So next let’s take a look at what the python language can do.

After we master python we can do some daily tasks alone: ​​small things like backing up your files, MP3s and the like.

Similarly, you can also do things such as websites and backends. Many large websites are developed using the Python language, such as YouTube, Instagram, and domestic Douban. Sohu.com is developed using python.

Similarly, you can also use python to do the game backend. There are many online game backends that are written in python.

Python can also be used to write crawlers to help writers obtain a large amount of information.

After introducing the relevant knowledge of the python language, let’s understand why

python is so popular?

The language python was only a niche language with little reputation a few years ago. However, why has python suddenly become popular in recent years? I think

the main reasons can be classified into the following three points:

(1). The rise of artificial intelligence and machine learning

In recent years, big data, artificial intelligence, and machine learning have attracted more and more attention, and many people are familiar with these concepts. In these aspects, because there are fewer talents, the salary of the position is higher than other similar positions, so many people are willing to learn this knowledge.

The Python language is simple and has a large number of external libraries, especially many libraries related to the above content, such as Matplotlib, Numpy, Pandas, and SciPy. These libraries are quite famous in Python. Use It is also more convenient to get up. Therefore, Python has also become the main language for big data, artificial intelligence, and machine learning and has a considerable number of learners.

(2). Python is simple and easy to learn
Compared with other programming languages, python is positioned as "elegant", "clear" and "simple".

Python adheres to a clear and consistent style in design, which makes Python an easy-to-read, easy-to-maintain, and widely-used language that is popular with a large number of users.

Python's design philosophy is "elegant", "clear" and "simple". Therefore, the Perl philosophy of "there are always multiple ways to do the same thing" is often unbearable among Python developers. The philosophy of Python developers is "do one thing in one way, and preferably only one way." When designing the Python language, if faced with multiple choices, Python developers will generally reject fancy syntax and choose clear syntax with little or no ambiguity.

It is precisely because of this that when beginners learn python, it is not only easy to get started, but they can also write complex programs after getting deeper. The same program in C language may require 1,000 lines of code, while Python may require only 20 lines of code. This is one of the main reasons why Python is easy to learn.

(3).The powerful functions of python

Although python is relatively simple to learn, its functions are also very powerful. It focuses on how to solve problems, a free and open community environment, and rich third-party libraries. There is no need to waste time building wheels. Various web frameworks, crawler frameworks, data analysis frameworks, and machine learning frameworks are all available, ready to use. If you are developing in Python, many functions do not need to be written from scratch, you can just use ready-made ones.

The above is all the content of this article. This article mainly introduces the relevant information of python, the advantages of python and why python suddenly transformed from a niche language to a language with considerable potential. language. I hope this article of mine can be of some help to you who are learning python.
