Week 8 Practical Activity - Programming Functions and Data Management

Analyze and implement a Python program based on hierarchical control flow functions related to student marks management. The assignment involves creating menu-driven functions with user input validation, decision structures, and data storage using dictionaries and lists. You are required to develop and complete specific function definitions, including a menu function controlling program execution, functions for entering student marks with validation, report generation functions, and display functions for specific student data. Additionally, you will implement a search function to ensure duplicate student entries are avoided. Further, you will enhance functions to handle collections of student data, display individual student details, and compute statistical reports such as average marks and identifying students below the average. The overall goal is to build a robust, user-interactive Python application following a hierarchical control flow, ensuring proper data validation, and clean function separations for modularity and clarity.

The task requires developing a Python application that manages student marks and generates reports based on user input. This application emphasizes the use of hierarchical control flow functions, user prompts, input validation through loops, data storage in dictionaries and lists, and modular function design. The program should continuously run until the user chooses to exit, with specific options to input student data, display reports, or exit the application.

Firstly, the core menu function must be implemented with a loop to facilitate persistent interaction with the user. When the program initializes, the menu displays options: (1) to input marks for a student, (2) to display reports, and (3) to exit. The menu function should invoke subordinate functions based on user choice, adhering to the control flow structure outlined. Notably, the menu should continue to prompt until the user explicitly chooses to exit (option 3), which is achieved using a while loop that checks for this termination condition. This ensures the application does not prematurely terminate on incorrect or unintended input.

Secondly, the functionality for entering student data must include prompts for student names and marks for three assessments: the Data Report (DF), Project, and Final Exam. Each mark must be validated within its acceptable range: 0-20 for the DF report, 0-30 for the Project, and 0-50 for the Final Exam. Using while loops, the program should repeatedly prompt until valid data is received, ensuring data integrity. The data structure chosen to store student information is a dictionary, where the keys are student names or IDs, and the values are lists or tuples of marks. Before adding new student data, the application invokes a search function to verify that the name or ID does not already exist, thus preventing duplicates. The search function should return True if a match exists and False otherwise, which helps maintain data consistency.

The function for displaying reports should prompt the user to select among several options, including retrieving various reports, such as students below average in each assessment, overall performance, and individual student details. Additionally, the user should have the option to return to the main menu. When a report function is invoked, it can compute necessary statistics like averages, compare individual marks, and display relevant student data accordingly. For display functions, passing data structures as parameters promotes modularity and consistency.

Further, specific functions like getBelowAvgDFReportMarksReport, getBelowAvgProjectMarksReport, getBelowAvgFinalExamMarksReport, and getBelowAvgOverallMarksReport need to be implemented to calculate the average of marks in respective assessments and identify students performing below these averages. These functions return lists or dictionaries containing statistical data and details of affected students, enabling comprehensive reporting.

The displaySelectedStudentsMarks function should accept a dictionary of students’ details as a parameter and display each student's information. This involves invoking another function, displayAStudentsDetail, which formats and outputs the details of an individual student based on the data passed in. This hierarchical structure supports organized and clear presentation of student records, facilitating user comprehension and data analysis.

Lastly, the implementation of the searchStudentMarks function plays a critical role in ensuring data uniqueness. This function takes a student name and the existing data storage as parameters, returning True if the student already exists, thus prompting the user to choose a different name. If not, it allows the process to continue for data entry. This helps prevent duplicate entries and maintains data integrity.

In conclusion, the project emphasizes the development of a control flow driven, user-interactive Python application for student marks management. Implementation should focus on using loops for input validation, decisions for control flow, data structures for storage, and modular functions for processing and report generation. Properly completed, the program will provide a comprehensive tool for managing student data, generating insightful reports, and maintaining data consistency.
