INTRODUCTION
            Python is a general-purpose interpreted, interactive, object-oriented, and high-level programming
                language. It was created by Guido van Rossum during 1985- 1990. Like Perl, Python source code is also
                available under the GNU General Public License (GPL). This tutorial gives enough understanding on Python
                programming language.
            Why to Learn Python?
            Python is a high-level, interpreted, interactive and object-oriented scripting language. Python is
                designed to be highly readable. It uses English keywords frequently where as other languages use
                punctuation, and it has fewer syntactical constructions than other languages.
            
                Python is a MUST for students and working professionals to become a great Software Engineer specially
                    when they are working in Web Development Domain. I will list down some of the key advantages of
                    learning Python:
                - Python is Interpreted − Python is processed at runtime by the interpreter. You do not need to
                    compile your program before executing it. This is similar to PERL and PHP.
 
                - Python is Interactive − You can actually sit at a Python prompt and interact with the
                    interpreter directly to write your programs.
 
                - Python is Object-Oriented − Python supports Object-Oriented style or technique of programming
                    that encapsulates code within objects.
 
                - Python is a Beginner's Language − Python is a great language for the beginner-level
                    programmers and supports the development of a wide range of applications from simple text processing
                    to WWW browsers to games.
