Challenge: Students Performance Tracking System

Problem statement

In the bustling world of education, keeping track of student performance is crucial for educators and administrators alike. Your task is to create a student performance tracker using Python that utilizes various advanced concepts such as iterators, comprehensions, sets, dictionaries, and generators. By implementing this solution, you will gain a deeper understanding of these powerful Python features while solving a practical problem.

You’ll be given a list of dictionaries, where each dictionary includes keys such as name, age, subjects, and grades. The subjects key maps to a set of subjects the student is enrolled in, and the grades key maps to a dictionary containing subject-grade pairs.

Tasks

Here are the tasks required to complete this programming challenge:

Calculating averages

• Write a function that takes the list of student dictionaries as input and returns an iterator that yields tuples of student names and their average grades.
• Use a generator expression to calculate the average grade for each student and yield the result.
• Ensure that the function handles cases where a student might not have any grades yet.

Filtering students

• Implement a generator function that takes the list of student dictionaries and a minimum average grade as inputs.
• This generator should yield the names of students who have an average grade above the given threshold.
• Utilize comprehension to filter students based on the minimum average grade requirement.
