Programming PYQs: Interface Python with MySQL (4 Marks) | Class 12 CS Revision 2026

Welcome back to the Class 12th Computer Science Quick Revision Course for the CBSE 2026 Board Exams! 🐍🗄️ In the previous video, we learned the syntax and the 4-step process of connecting Python to MySQL. In this video, we put that knowledge to the test by solving programming questions carrying a weightage of 4 marks on this topic from actual Previous Year CBSE papers. 🎯 Goal: To secure full 4 Marks in the "Interface Python with MySQL" section by solving standard board-level problems involving Deletion, Updation, and Selection. In this video, we solve PYQs covering: ✅ PYQ Type 1 (Deletion): Writing a function to delete a record based on user input (Using WHERE clause). ✅ PYQ Type 2 (Update): Modifying existing data (e.g., updating item price) and the mandatory use of db.commit(). ✅ PYQ Type 3 (Selection): Fetching and displaying records using fetchall() and loops. ✅ Common Mistakes: Where students lose marks in commit() and cursor execution. ✅ Exam Strategy: How to structure your code to get full marks. 📚 About this Course: This "Quick Revision Series" is designed for CBSE Class 12 Computer Science students who want to cover the entire syllabus efficiently. We focus on: • Concept Clarity in minutes. • Previous Year Questions (PYQs) integration. • Exam-oriented tips and tricks. 🎓 Don't miss a single topic!
