Definition of Python:

Python is a general-purpose, interpreted, high-level programming language, a Wikipedia definition. In clear terms, Python

1. High-level language – It is a human-readable language which easily understandable and easy to debug
2. Interpreted as well as compiled – Python is basically called an interpreted language, but can also be called a compiled interpreted language. In Python, first, all the source code is at once converted to byte code which is the action of the compiler, and then the byte code is executed by the compiler.
3. Python is also called a scripting language.

Why the name Python?

There was a TV show by the name Monty Python’s Flying Circus which was a very much popular fun show in the 1970s. While creating Python, Guido also used to read this show’s published scripts. Guido needed a short and a different name for this language, hence he named it “Python”.

Python Versions

1. Python 1.0V introduced in Jan 1994
2. Python 2.0V introduced in October 2000
3. Python 3.0V introduced in December 2008.
4. The current version is 3.8

Note: Python 3 won’t provide backward compatibility to Python2 i.e. there is no guarantee that Python2 programs will run in Python3.
