Python IntroductionPython's Past Life

Guido van Rossum in Google Python is an open-source, object-oriented scripting language that originated at the end of 1989 when CWI, a researcher at the Amsterdam National Institute of Mathematics and Computer science, Guido van Rossum needed a Advanced scripting language, which performs administrative tasks for its research team's amoeba distributed operating system. In order to create a new language, he drew a large amount of grammar from the Advanced Mathematical language ABC (all BASIC CODE) and borrowed from the System programming language Modula-3 the wrong language processing mechanism.         Van Rossum The new language as Python---from the BBC's popular comedy series "Monty Python". C Language Machine code execution Fast Python high-level language interpreter bytecode compilation interpretation execution Tiobe leaderboard 5 large and medium-sized enterprises with Python more, the application of a broader overall upward trend

Python app

graphics processing, with PIL, Tkinter and other graphics library support, can be easily graphics processing.

Mathematical Processing, The numpy extension provides a large number of interfaces to many standard math libraries,

Text Processing,the RE module provided by Python supports regular expressions and Sgml,xml analysis modules, and many programmers use Python for the development of XML programs.

database programming, programmers can communicate with databases such as Microsoft SQL Server,oracle,sybase,db2,mysql by following a module that follows the Python DB-API (database application programming Interface) specification. Python comes with a gadfly module that provides a complete SQL environment.

Network Programming, providing a rich module to support sockets programming, can quickly and easily develop distributed applications.

As a development language for Web applications, the latest XML technology is supported.

Multimedia applications, Python's Pyopengl module encapsulates the "OpenGL application Programming Interface" for two-and three-dimensional image processing. The Pygame module can be used to write game software.

Data Analysis System programming component integrates with Linux system to enable network services using the most extensive image processing using the secondary broad values Computational and scientific calculation cheap scientific calculator enterprise: Youtube,dropbox,quora,google,nasa
