Question $3$: Managing Academic Records and String Operations

Step $1$: Dictionary Creation $-$ Student Records:

$$ Create a dictionary named student$\_$records to manage student details.

$$ Populate the dictionary with student IDs as keys and dictionaries containing student information

$($name$,$ courses, grades$)$ as values.

Example:

student$\_$records $=\{$

$"$ST$001"$: $\{"$name$"$: "John Doe", "courses": $["$Math$",$ "Physics"$],$ "grades": $[85,78]\},$

$"$ST$002"$: $\{"$name$"$: "Emma Smith", "courses": $["$Physics$",$ "Biology"$],$ "grades": $[92,89]\},$

# Additional student records...

$\}$

Step $2$: String Operations $-$ Data Validation:

$$ Implement string operations for data validation and standardization:

$$ Validate student IDs:

$$ Ensure IDs follow a specific format $($start with $\text{'}$ST$\text{'}$ followed by

numbers$).$

$$ Implement error handling for invalid or inconsistent IDs.

$$ Standardize course names:

$$ Validate course names for consistent formatting.

$$ Handle potential duplicates or inconsistencies in course names.

$$ Error Handling:

$$ Implement robust error handling for any inconsistencies or invalid

data in the records.

Step $3$: Advanced Record Analysis:

$$ Perform advanced analysis on student records stored in the dictionary:

$$ Calculate Average Grades:

$$ Calculate the average grade for each course across all enrolled

students.

$$ Identify Exceptional Students:

$$ Identify students with exceptional performance $($highest grades$)$ in

each course.
