Python: The Most Advanced Programming Language for Computer Science Applications Akshit J. Dhruv, Reema Patel and Nishant Doshi Computer Science and Engineering, Pandit Deendayal Petroleum University, Gandhinagar, Gujarat Keywords: Python, Python libraries, Memory allocation, Data Structure, Framework. Abstract: In last few years, there has been an advancement in programming languages due to different libraries that are introduced. All the developers in this modern era prefer programming language that provides a built-in module/library which can make their work easy. This paper describes the advancement of one such language “Python” and it’s increasing popularity through different statistical data and graphs. In this paper, we explore all the built-in libraries for all different computer science domains such as Data Science, Machine Learning, Image Processing, Deep Learning, Natural Language Processing, Data Visualization, Cloud Computing, Speech recognition, etc. We have also included Memory management in Python. Different frameworks for Python which can make the front-end work easier are also mentioned. 1 INTRODUCTION 2 DATA STRUCTURE In 1991, Python language was developed by Guido Data structure means organization, management of van Rossum. There is an interesting story behind data and also it is a storage format which provides giving the name “Python” to the programming efficient access and modification. In general, it language. At the time of development of python, the contains relation among them, and the functions or developer was reading the script “Monty’s Python operations that can be applied to the data. Flying which is a BBC series. While reading this • Cython: It helps in improving the speed of the book he got an idea to name the programming implementation of the code. language as “Python” to have a short and unique • PYTables: It is used in maintaining name. Python is object- oriented, interpreted, and hierarchical datasets and is also used to interactive programming language. It provides high- maintain an extremely large amount of data. level data structures such as list, tuples, sets, • Tree Dict: It works as a container for python associative arrays (called dictionaries), dynamic to simplify the bookkeeping surrounding typing and binding, modules, classes, exceptions, parameters, variables, and data. It is very automatic memory management, etc. It is also used stable and fast at work. for parallel computing system and has a comparatively simple and easy syntax for coding Table 1: Different Data Structure in Python. and still it is a powerful programming language. Type Definition Symbol Example Python has the interpreter for java known as It is defined JPython, which is similar to the interpreter for C A list is a by square mutable data List=[1,2,3] language. Python has many advantages over any List braces [ ]. other languages, like it has varieties of library which structure, ordered sequence of reduces the code to one-third for programmer and element. due to this Python has reached at the +highest peak in terms of Machine Learning. Difficulty is faced by many while solving problems(Lawan et al, 2015), this research will help providing knowledge about different libraries and motivate them to use Python. 292 Dhruv, A., Patel, R. and Doshi, N.
