Python is a dynamic object-oriented, general purpose programming language which runs on many different computer platforms and mobile devices. Python is open source software and is published under an OSI-approved license. Python aims to be a language that is efficient, coherent, readable, and fun to use. Because Python is an interpreted language, Python programs run immediately without the need for lengthy compile and link steps.
History
Python was published by Guido van Rossum in 1991, and to this day, Guido remains the project leader.
Python reached version 1.0 in 1994.
Syntax
Hello World
The code for traditional "hello world" program can hardly be simpler:
print 'Hello World'
This is either put in a file "hello.py",say, and executed with
python hello.py
from the usual command line of the operating system or typed directly in the interactive Python environment (Python command line or IDLE).
Implementations
Python's official distribution is known as CPython. It's written in C and functions as a virtual machine interpreting bytecode-compiled Python programs. Jython is an implementation for the Java Virtual Machine, which can run either standalone (like CPython) or as an embedded scripting engine. IronPython is an implementation for the Common Language Runtime (.NET and Mono). PyPy is an implementation written in Python that targets several backends, including C, LLVM, JavaScript, JVM and CLR.
