Recently, Python has been widely praised as a powerful and general programming language. It has very clear syntax features and is suitable for a variety of operating systems. It is very popular in the world and is getting more and more applications.

1. Brief introduction

Python, an object-oriented, literal translation computer programming language, has a history of nearly two decades. It contains a set of fully functional standard libraries that can easily accomplish many common tasks. Its syntax is simple, and unlike most other programming languages that use curly braces, it uses indentation to define statement blocks.

Python supports imperative programming, object-oriented programming, functional programming, side-oriented programming and paradigm programming.

two。 Origin

The founder of Python is Guido Van Rosum (Guido van Rossum).

On the origin of Python, Guido van Rosum wrote in 1996: six years ago, in December 1989, I was looking for an "extracurricular" programming project to pass the time around Christmas. My office will be closed, but I have a home computer and I don't have many other things. I decided to write an interpreter for a new scripting language I was working on at the time, which is a descendant of the ABC language and would be attractive to UNIX / C programmers. As a slightly irrelevant person and a fan of Monty Payson's flying circus (Monty Python's Flying Circus), I chose Python as the title of the project.

In 2000 he wrote that Python's predecessor, the ABC language, was inspired by SETL-Lambert Meertens spent a year with the SETL team at New York University before completing the final design.

3. Philosophy and orientation

Python's design philosophy is "elegant", "clear" and "simple". The philosophy of Python developers is "one way, preferably only one way to do one thing." When designing a Python language, if faced with a variety of choices, Python developers generally reject fancy syntax and choose syntax that has no or little ambiguity. These principles are called "Python maxims". Run import this within the Python interpreter to get a complete list.

4. Application scope and function

As a simple, interpretive, interactive, portable, object-oriented super-high-level language. Python has an interactive development environment because Python is interpreted and run, which greatly saves time per compilation. Python syntax is simple, and there are several advanced data structures built in, such as dictionaries, lists, etc., which make it easy to use, can be learned in an afternoon with programming experience, and can be mastered by ordinary people within a week. Python has the characteristics of most object-oriented languages and can be completely object-oriented programming. It can run on many kinds of OS, such as MS-DOS, Windows, Windows NT, Linux, Soloris, Amiga, BeOS, OS/2, VMS, QNX and so on.

1. Programming language

Python can be used as a batch language, write some simple tools, process some data, and debug the interface of other software. Python language can be used as a functional language to develop artificial intelligence programs and has most of the functions of Lisp language. Python language can be used as a process language for our common application development, and it can be used the same as VB and other languages. Python language can be used as an object-oriented language, which has the characteristics of most object-oriented languages. It is often used as a prototype development of large-scale application software, and then rewritten with C++, and some are directly developed with Python.

2. Database

Python is also good at databases and can connect to a variety of databases for data processing, from commercial databases to open source databases. For example: Oracle,Ms SQL Server and so on. There are several interfaces that can connect to the database, including at least ODBC. There are many companies that adopt the structure of Python+MySql, and of course we are no exception. Therefore, mastering Python enables you to take full advantage of object-oriented features and add power in database processing.

3. Windows programming

Python can be used not only in Unix-type operating systems, but also in Windows systems. By adding a PythonWin module, you can call and establish a variety of resources in the form of COM, including calling the registry, ActiveX controls and a variety of COM work. The most common example is through the program to deal with Office documents and automatically generate documents and charts.

With Python, you can also use the py2exe module to generate exe applications. There are many other day-to-day maintenance and management tasks that can also be assigned to Python to reduce the workload of maintenance. With Python, you can also develop GUI programs like VB,VC,Delphi, but they can be executed on multiple platforms. This is not inferior to Java in many ways.

4. Multimedia

Using PIL, Piddle, ReportLab and other modules, you can process images, sound, video, animation, etc., so as to add brilliance to your program. The generation of dynamic charts and statistical analysis charts can be completed through Python. In addition, there is OpenGL. With the PyOpenGl module, you can write 3D scenes very quickly.

5. Scientific calculation

Python can widely play a unique role in the field of scientific computing. There are many modules that can help you work efficiently in computing giant arrays, vector analysis, neural networks, and so on. Especially in education and scientific research, it can give full play to its unique advantages.

6. Network programming

Python can easily complete the work of network programming, provides a large number of solutions and modules, can be very convenient to customize their own server software, whether it is cUnix s or bUnip s mode, there are good solutions.

7. Graphical user interface

Python can be very convenient to achieve GUI programming, through Tkinter,wxPython,QT and other modules, you can write a powerful cross-platform user interface program as needed.

8. Game programming

Python has been an auxiliary tool for game programming since a long time ago. Played an important role in Star Wars. Industrial Light and Magic (Industrial Light), which works as stunts and animators in "Abyss", "Star Trek" and "Indiana Jones" blockbusters, uses Python to produce commercial animation. At present, great game programs can be written through Python.

5. Development environment

There are many development tools of Python program, such as IDLE,eclipse+pydev,pycharm and so on. Through these tools, you can get your work done more quickly.

Integrated Development Environment (IDE):

1. IDLE: this is included in Python and can basically meet the general development needs.

2. PyCharm:PyCharm is a Python IDE with a complete set of tools that can help users improve their efficiency when developing in Python, such as debugging, syntax highlighting, Project management, code jumping, smart tips, automatic completion, unit testing, version control.

3. Eclipse+pydev:Eclipse is the IDE of JAVA. For friends who have experience in java development, the cost of learning is small.

6. Embedding and expanding

Python can be embedded in other applications, or an extension module can be written through Cpicket +, so as to improve the running speed of the program or complete the work that can only be done through Chammer +. Now Python can be combined with C # and integrated into Visual Studio to realize Microsoft's .net idea. If you can speak C and then learn Python, it will be a great choice.

If you have mastered Python and want to use it in Java, you can use Jython. Jython is a Python implemented in Java language. In this way, as long as you follow the syntax of Python, you can call various class libraries of Java and quickly write programs based on Java. That is, through Jython, write Java programs. In this way, the function of Java can be realized more quickly. Python is similar to Java in object orientation.

7. Enterprise and government application

At present, Python has successfully implemented enterprise applications. In the world, many companies have adopted Python to develop and apply enterprise software, such as ERP and CRM. At the same time, through Python technology, many government applications have been successfully realized. For example:

Zope: an application server with advanced features such as content management, team development, XML, object-oriented, SOAP interface, and open source

Gadfly: an object-oriented relational database written in Python, small, fast, portable, with most of the SQL language features, and open source.

Some more famous companies are also developing with Python, such as Microsoft, IBM, Red Hat Douban and so on.

8. Digital gathering Media chooses Python Development

To sum up, Python has stood the test of the market and is becoming more and more popular among developers.
