In the ever-evolving world of technology, Python has emerged as one of the most versatile and popular programming languages. Its simplicity, readability, and powerful libraries make it an ideal choice for both beginners and experienced programmers. This book sets the stage for a comprehensive exploration of Python, covering a wide range of fundamental topics that are essential for anyone looking to master this dynamic language. The journey begins with an introduction to the basics of Python. From variables and data types to operators and control structures, you'll gain a solid understanding of the core elements of Python. Continues with Data Structures, Functions, Packages, File Handling, Exception Handling, Object-Oriented Programming in Python and Web Operations in Python

Graphics are defined as any sketch or a drawing or a special network that pictorially represents some meaningful information. Computer Graphics is used where a set of images needs to be manipulated or the creation of the image in the form of pixels and is drawn on the computer. Computer Graphics can be used in digital photography, film, entertainment, electronic gadgets, and all other core technologies which are required. Computer Graphics can be used in UI design, rendering, geometric objects, animation, and many more. Multimedia is content that uses a combination of different content forms such as text, audio, images, animations, video and interactive content. This technology is now largely adopted by most computer based applications to bridge the gap between a human user & the computer. This textbook discusses the concepts, principles and applications of Computer Graphics in a simple, precise and systematic manner. It explains how to manipulate visual and geometric information by using the computational techniques. It also incorporates several experiments to be performed in computer graphics and multimedia labs.

The book discusses the concepts of machine learning with respect to supervised and unsupervised algorithms. Every topic has been discussed with an example case study. The concept of data modelling with respect to various methods were discussed with examples. The introduction on NOSQL is also added as the feather to the cap, its installation process in Cloud Environment and execution of Mongo DB commands were discussed.The concept of Distributed file storage, Overview of Hadoop and its architecture, role of name node and data node in HDFS systems were discussed. The basics installation procedure Hadoop in Windows was explained in a step by step manner with appropriate snapshots and coding. The role of Map reduce algorithms and Hbase architecture were discussed.This book is prepared for easy understanding of the learners about the basic concepts of data science and analytics.
