The most powerful Python King (1)--python Introduction

1.Python Introduction

Python is a high-level programming language for interpreting, object-oriented, and dynamic data types.

Python was invented by Guido van Rossum at the end of 1989 , and the first public release was released in 1991 year.

Like the Perl language , the Python source code also follows the GPL (GNU general public License) protocol.

Python is a high-level scripting language that combines explanatory, compiled, interactive, and object-oriented.

Python 's design is highly readable, with English keywords often used in other languages, some punctuation in other languages, and it has a more distinctive grammatical structure than other languages.

Python is an interpreted language: This means that there is no compilation in the development process. Similar to the PHP and Perl languages.

Python is an interactive language: This means that you can Execute your program in a Python prompt directly interacting with the execution.

Python is an object-oriented language : This means that python supports object-oriented styles or code encapsulation in object programming techniques.

Python is a beginner's language:python is a great language for novice programmers, and it supports a wide range of application development, from simple word processing to WWW Browser again to the game.

2.Python Development History

Python  guido  VAN ROSSUM&NBSP,

Python  abc , modula-3 , c c++ algol-68 , smalltalk unix shell &NBSP, and other scripting languages, etc.

Like the Perl language, thePython Source code also follows the GPL (GNU general public License) protocol.

Now that Python is being maintained by a core development team,Guido van Rossum still occupies a vital role in guiding its progress.

3.Python features

3.1. easy to learn:Python has relatively few keywords, simple structure, and a well-defined syntax that is easier to learn.

3.2. easy to read:Python code definition is clearer.

3.3. easy to maintain:the success ofPython is that its source code is fairly easy to maintain.

3.4. a wide range of standard libraries:One of the biggest advantages ofPython is the rich library, cross-platform, UNIX,Windows and the Macintosh compatible very well.

3.5. Interactive mode: Interactive mode support allows you to enter code execution from the terminal and get results from the language, interactive testing and debugging code snippets.

3.6. Portable : Based on its open source features,Python has been ported (that is, making it work) to many platforms.

3.7. Extensible : If you need a critical code that runs very fast, or if you want to write some algorithms that you don't like to open, you can use C or C + + to complete that part of the program, and then from your Python called in the program.

3.8. database:Python provides the interface for all major business databases.

3.9.GUI Programming:Python support GUI can be created and ported to many system calls.

3.10. embeddable : You can embed Python into a C + + program that allows users of your program to get " scripting " capability.
