Python is an interpreted, high level and general purpose programming language. 
Python's design philosophy emphasizes code readability with its notable use of significant whitespace.
 Its language constructs and object oriented approach aim to help programmers write clear,
 logical code for small and large-scale projects.[28]
Python is dynamically typed and garbage collected. 
It supports multiple programming paradigms, including structured ( particularly procedural ) object oriented,
 and functional programming. Python is often described as a "batteries included" language due to its comprehensive standard library.
Python was created in the late 1980s, and first released in 1991, 
by Guido van Rossum as a successor to the ABC programming language. Python 2.0, released in 2000, 
introduced new features, such as list comprehensions and a garbage collection system with reference counting,
