Computer Science with Python: Textbook for CBSE class 11(as per 2023-24 syllabus)
This book, Informatics Practices with Python for Class XI (065), has been prepared in accordance with the latest CBSE syllabus for the 2023-24 academic session. The book focuses on teaching Python language to help students learn programming concepts and develop problem-solving skills and RDBMS operations to better organize and implement efficient database systems. With easy-to-understand examples, self-explanatory diagrams and other such tools, the student learns to design the logic for a program and then implement that program using Python. Besides tested, debugged and error-free codes with screenshots, ample concise and practical example programs derived from real-life situations have been provided in the book. CTM (Commit to Memory), Learning Tips and Points to Remember for easy recall of important terms and concepts are other notable features of the book.
Strictly adhering to the CBSE curriculum and guidelines, the book has been divided into four units:
