Introduction and System Requirements
Explanation of the Code:
1. Classes:
Student: This class represents a student with
•
attributes for name, roll number, and marks. It
has a __str__ method to format the output
when printing.
• StudentRecordManager: This class
handles all operations related to student
records, including loading, saving, adding,
searching, updating, deleting, and displaying
records.
2. File Handling: The application uses a text
file (student_records.txt) to store student records.
Each record is stored in a comma-separated
format.
3. Methods:
• load_records(): Loads records from the text
file and returns them as a list
of Student objects.
• save_records(records): Saves the list
of Student objects back to the text
file.
• add_record(): Prompts the user to
input a new student record and
appends it to the list.
• search_record(): Searches for a
student record by roll number and
displays it if found.
• update_record(): Updates an existing
student record based on user input.
