Cracking the mystery of the wide application of Python Programming Language

If I want to know the Python programming language, I need to know its characteristics. Next, let's take a look at the characteristics of the Python programming language. Python is not a programming tool, but an object-oriented explanatory computer programming language. It is also a powerful and complete general-purpose language.

This language has a very simple and clear syntax. It is suitable for completing various high-level tasks and can run in almost all operating systems. At present, technologies based on this language are rapidly developing, the number of users has expanded dramatically, with a large number of related resources.

Features of the Python programming language:

Simple: Python is a language that represents the simple ideology. Reading a good Python program is like reading English, although the English requirements are very strict! The essence of this pseudo-code in Python is one of its biggest advantages. It enables you to focus on solving problems rather than understanding the language itself.

Easy to learn: just as you will see, Python is extremely easy to use. As mentioned above, Python has extremely simple syntax.

Free and Open Source: the Python programming language is one of the FLOSS free/open source software. Simply put, you can freely publish copies of the software, read its source code, make changes to it, and use part of it in new free software. FLOSS is based on the concept of a group sharing knowledge. This is one of the reasons why Python is so excellent-it was created and often improved by a group of people who want to see a better Python.

High-level Language: when writing a program in Python, you do not need to consider the underlying details such as how to manage the memory used by your program.

Portability: because of its open source nature, the Python programming language has been transplanted on many platforms and changed to enable it to work on different platforms ). If you are careful not to use system-dependent features, all your Python programs can run on any of the following platforms without modification. These platforms include Linux, Windows, FreeBSD, Macintosh, Solaris, OS/2, Amiga, AROS, AS/400, BeOS, OS/390, z/OS, Palm OS, QNX, VMS, Psion, Acom risc OS, VxWorks, PlayStation, Sharp Zaurus, Windows CE, and even PocketPC and Symbian!

Explanation: This requires some explanation. A program written in a compiled language such as C or C ++ can be converted from the source file C or C ++ to the binary code of the language used by your computer, 0 and 1 ). This process is completed by the compiler and different tags and options. When you run your program, the connection/reprinter software copies your program from the hard disk to the memory and runs it. Programs Written in Python do not need to be compiled into binary code. You can run the program directly from the source code.

Inside the computer, the Python language interpreter converts the source code into an intermediate form called bytecode, and then translates it into the machine language used by the computer and runs it. In fact, because you no longer need to worry about how to compile the program, how to ensure that the correct library is reprinted, and so on, all of this makes Python easier to use. Because you only need to copy your Python program to another computer, it can work, which makes your Python program easier to transplant.

Object-oriented: Python supports process-oriented programming and object-oriented programming. In a "process-oriented" language, a program is built by a process or a function that is only reusable code. In the "Object-Oriented" language, a program is built by combining data and functions. Compared with other major languages such as C ++ and Java, Python implements object-oriented programming in a very powerful and simple way.

Scalability: If you need a piece of key code to run faster or want some algorithms not to be made public, you can write some of your programs in C or C ++, then use them in your Python program.

Embedding: You can embed the Python programming language into your C/C ++ program to provide script functions to your program users.

Rich libraries: the Python standard library is indeed huge. It can help you deal with various jobs, including regular expressions, document generation, unit testing, threads, databases, web browsers, CGI, FTP, e-mail, XML, XML-RPC, HTML, WAV Files, password systems, and GUI graphics user Interface), Tk, and other system-related operations. Keep in mind that all these functions are available as long as the Python programming language is installed. This is called Python's "full functionality" concept. In addition to the standard library, there are many other high-quality libraries, such as wxPython, Twisted, and Python image libraries.

Summary: The Python programming language is indeed a wonderful and powerful language. It combines high performance with features that make programming simple and interesting. However, I found that there are not many people currently using it, all of which are in English ......
