Python MarkSheet Management System
This project is Developed by:
Student Name : Mitushi Chauhan
School : RKVM, Gwalior
This is a project to maintain student details like:
roll
name
Marks of physics
Marks of chemistry
Marks of maths
Marks of computer
Marks of english
total
per
grade
This project will clear the basic concepts of project development for student. Using this project as base the fields can be changed and a large project can be developed.
This project uses binary file handling to store and maintain the student data.
Here we have options for
- Adding a new record in the binary file
- Display all the records from the file
- Search a record on the basis of roll no
- Searh a record on the basis of name
- Modify a record on the basis of roll no
- Delete a record by roll no
