Python is a high level, widely used general-purpose language. Its design emphasizes on code readability, and its syntax allows the programmers to express concepts in fewer(less) lines of code than would be possible with other languages g. C++ or Java
Python 2.7 supports multiple paradigms of programming, including imperative, object-oriented, and functional programming. Python features a very dynamic type system and automatic memory management and has a very comprehensive, large standard library.
