: Often sold as a combo including the main textbook for theoretical depth and a practical book for hands-on laboratory exercises. "Computer Science with Python" by Sumita Arora is
| Unit | Chapter Name | Key Topics Covered | | :--- | :--- | :--- | | | Python Revision Tour | This unit revisits core Python concepts from Class 11, including variables, data types, conditional statements, and loops, forming the foundation for advanced study. | | I | Python Revision Tour II | Continues the revision with a focus on strings, lists, tuples, and dictionaries, ensuring students have a strong command of fundamental data structures. | | I | Working with Functions | Dives deep into user-defined functions, including parameters, arguments, return values, and variable scope (global vs. local). | | I | Using Python Libraries | Introduces the concept of importing and using pre-built libraries and modules to enhance code functionality and efficiency. | | I | File Handling | Covers permanent data storage using text, binary, and CSV files. Important file modes ( r , w , a ) and functions ( read() , write() ) are explained in detail. | | I | Recursion | Explores the concept of recursion, where a function calls itself, using classic examples like factorial and the Fibonacci series. | | I | Idea of Algorithmic Efficiency | An introduction to the principles of writing efficient code, focusing on time and space complexity analysis. | | I | Data Visualization Using Pyplot | Teaches students how to present data graphically using the Pyplot library, covering various charts and plots. | | I | Data Structures: Stacks & Queues | Focuses on the implementation of fundamental data structures using Python lists, with an emphasis on LIFO (Stack) and FIFO (Queue) operations. | | II | Computer Networks (I & II) | Covers the evolution of networks, types of networks (LAN, MAN, WAN, PAN), network topologies, transmission media, and network devices like routers and switches. | | III | MySQL SQL Revision Tour | A comprehensive review of Structured Query Language (SQL), covering DDL ( CREATE, ALTER, DROP ) and DML ( INSERT, UPDATE, DELETE, SELECT ) commands. | | III | More on SQL | Delves into advanced SQL concepts such as aggregate functions ( COUNT, SUM, AVG, MIN, MAX ) and the GROUP BY and JOIN clauses for complex queries. | | III | Interface Python with MySQL | Teaches the practical skill of connecting Python programs with a MySQL database to execute SQL queries and fetch/manipulate data through Python scripts. | | Appendices | Society, Law & Ethics | Discusses important real-world topics like cyber safety, intellectual property rights, and the ethical use of technology. | | Unit | Chapter Name | Key Topics
to reinforce conceptual understanding. Application-based Questions to build logical thinking. local)
Sumita Arora's approach is renowned for breaking down complex computational logic into digestible modules.
DDL and DML commands. Students master commands like CREATE , DROP , ALTER , INSERT , UPDATE , DELETE , and complex SELECT queries utilizing GROUP BY , HAVING , and ORDER BY .
No. However, some states (like Kerala, Tamil Nadu) provide free digital textbooks through their state boards, but for CBSE, Sumita Arora is a private publication—no legal free full PDF exists.
