Liuxingyuan Classroom: What are the characteristics of Python? Comparison of advantages and disadvantages of Python programming language!

Python was designed by Guido van Rossum at the National Institute of Mathematics and Computer Science in the Netherlands in the late 1980s and early 1990s. Python is not American, so babies don't have to be afraid of getting stuck by Americans at every turn.

Python itself is developed from many other languages, and the Python source code follows the GPL (GNU General Public License) agreement. Currently Python is maintained by a core development team.

Let's take a look at the introduction of Baidu Encyclopedia:

> > Python is a computer programming language. It is a dynamic, object-oriented scripting language, originally designed for writing automation scripts (shells), and is increasingly used for independent, large-scale projects as versions are updated and new features of the language are added. development. Can be applied to the following fields: Web and Internet development, scientific computing and statistics, education, desktop interface development, software development. >

Let's take a look at the introduction of Python's official website:

> > Python is powerful... and fast; >

> > plays well with others; >

> > runs everywhere; >

> > is friendly & easy to learn; >

> > is Open. >

> > These are some of the reasons people who use Python would rather not use anything else. >

These are the reasons why so many people use Python and nothing else.

1. What are the characteristics of Python?

Python is the language closest to artificial intelligence, and now is a period of rapid development of artificial intelligence, so the field of python application is very wide.

It focuses on algorithms and learns algorithm implementations more deeply and clearly. Python is simple, elegant, and clear. Google, Instagram, Douban, Zhihu, these elegant Internet companies are all using it.

The unique charm of python can be summed up in three sentences:

The python language also has many unique features, which can be summarized as follows:

• Python is an interpreted language. This means that Python programs do not need to be compiled, similar to PHP, JS, but there will definitely be some speed impact. It is said that Microsoft is going to embed Python into Excel as a script, similar to VBScript, and the prospect of such an application is really tempting. Python is an interactive language. This is similar to dos, of course, much more powerful than dos, you can program and execute directly. The advantages of this are obvious. For example, in embedded programming, the compiled language in C/C++ mode was generally used in order to improve the speed. In some cases, it is more flexible to reload the script by prompting the human-computer interaction. Python is an object-oriented language. This means that Python's support for classes, inheritance, and encapsulation is very good. Python is very easy to learn. The keywords are very few and the syntax structure is simple. Python programs are very easy to read and maintain. Python's code structure is very clear. Python has very extensive standard class library support. Friends who often write programs must know what the class library means. Of course, it will get twice the result with half the effort. Python is cross-platform and open source. Whether it is in Linux, Unix, Windows, or embedded, there are very good applications, and it is easy to meet the effect of one development and running everywhere. Python can even be embedded in C\C++ programs and used as scripts. Python's support for databases is very good. Various mainstream commercial databases and various open source databases have corresponding Python interfaces.

2. Comparison of the advantages and disadvantages of the Python programming language

Advantages of Python programming language

A major advantage of python is that it has an extensive library of code for various areas such as string manipulation, regular expressions, unit testing, threading, image processing, operating system interfaces and protocols, and web service tools. The existence of these codes eliminates the need to write verbose code, which saves a lot of time.

Python has extensible application integration, allowing programmers to put their code into other languages ​​such as C, C++ or Java through Jython. Also, if you want to add scripting capabilities to another language, you can put the Python code in the source code of the other language. Since python runs on all modern operating systems that use the same byte code, it can handle other markup languages.

The Python programming language is easy to learn and use, clean, readable, and well-structured. The language focuses on code readability and has supporting libraries that make development faster and maximize programmer productivity.

Python's unit testing framework and enhanced control capabilities improve the speed and productivity of most applications, making it ideal for building multi-protocol networking applications.

Disadvantages of Python

Although present in desktops and servers, it is rarely seen in smartphone-based applications, despite the presence of Brython. This is because it is not safe. If you're using it to develop mobile apps, make sure to use a python VPN for maximum security.

Programmers using python are used to it, and because it doesn't require much coding, they have a hard time using other languages ​​that require a lot of coding.

Python is dynamically typed, which eliminates the need to declare variable types when writing code, increasing the risk of runtime errors.

3. What is the application prospect of Python?

One of the most important reasons why Python has become the most popular language is the application of Python in the field of artificial intelligence. In recent years, the rapid development of artificial intelligence, because Python is relatively easy to use, interactive and other excellent performance, just suitable for applications in the field of artificial intelligence.

Python is very easy to use, and can do many things, WEB development, machine learning artificial intelligence, data analysis, quantitative investment, crawlers, etc., can basically be applied to all walks of life, and everyone is working on PYTHON-based libraries, making the PYTHON language become A language that can be used directly is more like a tool, such as machine learning. The theory may be very complicated, but it can actually be implemented in PYTHON with only a few lines of code, without spending too much time on coding. , After learning python, I no longer want to write other languages, python is getting more and more popular now.
