In this A-Level Computer Science class, Ahmed Elmalla guides Luana through three essential programming concepts: file handling, recursion, and object-oriented inheritance. The session begins with a file-writing exercise, where Luana learns how to format and save structured data using Python’s join() method. Ahmed explains common issues with file handling in REPL platforms and how to resolve them using flags and file reopen strategies.
The lesson then shifts to recursion, using the factorial function as a foundational example. Ahmed emphasizes the importance of base cases and how recursion compares with loops in both logic and efficiency. Finally, the class introduces inheritance, showcasing how to structure part-time and full-time employee classes using a shared Employee base class and the super() function for clean, reusable code.
This class is ideal for students preparing for object-oriented programming and algorithm questions in the A-Level syllabus.
