CLASS 12 PYTHON PROJECT

Python Student Database Management System 2

This project maintains student details like:

rollno
name
m1
m2
m3
total
per

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
