                 Python is a high-level programming language. It has a simple language syntax that makes it
                 easy to read and write. It was developed by Guido Van Rossum in 1991 at the National Research
                 Institute for Mathematics and Computer Science in Netherlands. Various versions of Python have
                 been released till date starting from version 1.0. We will learn to use Python 3.7 version which
                 is used in various application areas such as:

                    Web Application
                    Scientific and Numeric Computational Applications
                    Games

                    Image Processing and Graphic              Clickipedia
                    Designing applications
                                                                Guido Van Rossum named the language
                    Network Programming
                                                                Python as he was a fan of the comic
                    Artificial Intelligence

                     FEATURES OF PYTHON


                    Easy to learn: Python has relatively few keywords, simple structure and a clearly-defined
                    syntax.
                    Easy to read: Python code is just like English language.
                    Case Sensitive: Python is a case-sensitive language. In Python, ‘pay’ and ‘PAY’ are not the
                    same. They are interpreted differently.

                    Free and Open Source: Python is an example of open-source software. It means you can freely
                    distribute copies of this software, read its source code and make changes to it.
