Maintainability is the ease with which a programming language can be maintained so as to find out bugs or their cause, correct the bugs or their cause. It is easier to maintain a well design and implemented object-oriented system than well designed imperative system. This is due to the facts that object oriented language is more complicated than imperative language because of the use of polymorphism and inheritance; these make it difficult to identify errors and their causes as it cause indirection in the program.
All system implementation requires both good interactive performance and good run time performance. It is difficult to satisfy these needs using a pure object oriented language since it requires a lot of optimization such that interactive performance suffers; the performance can be improved by adopting adaptive recompilation which helps improve the system’s responsiveness to programming changes. Lack of dynamically dispatched calls in an imperative language like C improve performance since they do not encourage factoring codes into small, reusable units, thereby reducing the frequency of the expensive operations. Frequent calls not only hinder optimization and slow down execution with dispatch overhead per second.
Python Programming Language. Python programming language includes various features of modern programming languages such as it is an interactive, explained, and programming language which works on objects. Additionally, it includes programming exception, components, extremely elevated level of dynamic data types, brisk typing and class level functionalities.
The various programming languages available for computer programming are classified according to the paradigm in which they operate. Each programming paradigm is different in style, concept and methodology from others. Different paradigms are suitable for different purposes egg – object oriented paradigm considers any program written as a collection of various objects that interact with each other, database programming paradigm is ideal if the program is intended to handle large amount of data and logic and constraint based programming is the most suited for search problems.
In this scenario, the instructions are given to the computer to carry out a specific task. In addition, these instructions are provided to the computer according to the rules of the programming language. At the present, there are numerous programming languages, which can be used to develop a wide variety of software applications (Shelly et al., 2005; Norton, 2001).
As the computer science is an evolving and dynamic discipline, therefore, it is difficult to categorize the already developed computer languages. Some of the authors have classified the computer languages into three (3) categories include: machine level language, assembly level language and high level language (Venit and Drake, 2010).
Java is an object-oriented programming language created in 1995 by Sun Microsystems for the development of software applications and interactive programs or applets which are commonly used in the internet for animation purposes. In today's evolution in mobile industry, Java contributes more advancement in the making of mobile applications and software.
The main reasons for this were the cost and the lack of knowledge about computers to the common man. In those days development of programming languages were at the initial stages. Because of the cold war the computer rooms were heavily guarded and research on software engineering was not given much importance.
Though every language is built on the common ground of communicating “Efficiently and Effectively” with the machine, each language has its own merits and demerits. Some were developed with a specific purpose, some with a specific business application, some for scientific purposes, and some to overcome the demerits of other languages.
However, the history of programming is related and studied more in relation with computing and how the two segments of the technology industry, computer hardware and associated programming languages, developed in parallel. The history shows that the evolution has certainly not stopped and newer technologies and tools appear frequently.
The author states that Python programming language was created by Guido van Rossum and this development was supported and encouraged by various other programming paradigms such as by ABC, Haskell, Java, LIST programming, Icon and Perl programming languages. In python, programs are written using an indentation technique.

Programmability of programming language refers to the ability of that language to modify itself as per the programmer’s requirements. Object oriented programming language, like java, provides an easy programmability procedure. Codes developed in one module can be reused in another module. …
