Overview of Python Programming Language

Python is an easy to learn, powerful programming language. It has efficient high level data structures and a simple but effective approach to object-oriented programming. Python's elegant syntax and dynamic typing, together with its interpreted nature, make it an ideal language for scripting and rapid application development in many areas on most platforms.

The Python interpreter and the extensive standard library are freely available in source or binary form for all major platforms from the Python Web site, http://www.python.org/, and can be freely distributed.

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 on many different computers and operating systems: Windows, MacOS, many brands of Unix, OS/2.

·         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,

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.
