Poster with code for ( introductory programming) assignment

This assignment requires you to design and implement a working Python program based on your allocated scenario (for me, Scenario 5C), ensuring it meets all functional requirements such as correct data handling, validation, persistence, and reporting. You must structure your solution using appropriate data structures and clear program logic, handle edge cases (e.g., invalid input or overspending), and ensure the program runs correctly. In addition to the code, you must create a one-page poster explaining your problem context, inputs, program behaviour (pseudocode or flowchart), chosen data structures with justification, persistence approach, constraints, and a short evaluation. Both the Python file and the poster must be submitted on Blackboard before the deadline, and I will attend a viva where I explain and justify my design decisions so I would like a small brief in another page explaining .
