Python

Python is a clear and powerful object-oriented programming language, comparable to Perl, Ruby, Scheme, or Java.

Some of Python's notable features:

• Uses an elegant syntax, making the programs you write easier to read.
• Is an easy-to-use language that makes it simple to get your program working. This makes Python ideal for prototype development and other ad-hoc programming tasks, without compromising maintainability.
• Comes with a large standard library that supports many common programming tasks such as connecting to web servers, searching text with regular expressions, reading and modifying files.
• Python's interactive mode makes it easy to test short snippets of code. There's also a bundled development environment called IDLE.
• Is easily extended by adding new modules implemented in a compiled language such as C or C++.
• Can also be embedded into an application to provide a programmable interface.

• Runs anywhere, including Mac OS X, Windows, Linux, and Unix.

• Is free software in two senses. It doesn't cost anything to download or use Python, or to include it in your application. Python can also be freely modified and re-distributed, because while the language is copyrighted it's available under 

Some programming-language features of Python are:

• A variety of basic data types are available: numbers (floating point, complex, and unlimited-length long integers), strings (both ASCII and Unicode), lists, and dictionaries.
• Python supports object-oriented programming with classes and multiple inheritance.
• Code can be grouped into modules and packages.
• The language supports raising and catching exceptions, resulting in cleaner error handling.
• Data types are strongly and dynamically typed. Mixing incompatible types (e.g. attempting to add a string and a number) causes an exception to be raised, so errors are caught sooner.
• Python contains advanced programming features such as generators and list comprehensions.
• Python's automatic memory management frees you from having to manually allocate and free memory in your code.
