Python is an interpreted, interactive, object-oriented programming language.It combines remarkable power with very clear syntax written by Guido van Rossum. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. Python was designed to be a highly readable language. It aims toward an uncluttered visual layout, using English keywords frequently where other languages use punctuation.
