What is Python?

Python is a powerful high-level, object-oriented programming language created by Guido van Rossum and first released in 1991. Python's name is derived from the television series Monty Python's Flying Circus, and it is common to use Monty Python reference in example code. This language is now one of the most popular languages in existence. This language is now one of the most popular languages in existence. Since 2003, Python has consistently ranked in the top ten most popular programming languages as measured by the TIOBE Programming Community Index.
Python Tutorial
Its syntax is very clean, with an emphasis on readability and uses standard English keywords . A basic understanding of any of the programming languages is a plus. Moreover, an experienced developer in any programming language can pick up Python very quickly. Python is a cross-platform programming language, meaning, it runs on multiple platforms like Windows, Mac OS X, Linux, Unix and has even been ported to the Java and .NET virtual machines. Python interpreters are available for many operating systems, allowing Python code to run on a wide variety of systems. Most Python implementations (including CPython) include a read–eval–print loop (REPL), meaning they can function as a command line interpreter, for which the user enters statements sequentially and receives the results immediately. The design of Python offers some support for functional programming in the Lisp tradition. Python is indeed an exciting and powerful language. It has the right combination of performance and features that make writing programs in Python both fun and easy.
