Student management system in Python

Problem Statement: Write a program to build a simple Student Management System using Python which can perform the following operations:

Approach: Below is the approach to doing the above operations:

1. Accept – This method takes details from the user like name, roll number, and marks for two different subjects.

# Method to enter new student details def accept(self, Name, Rollno, marks1, marks2 ): # Creates a new class constructor # and pass the details ob = Student(Name, Rollno, marks1, marks2 ) # list containing objects of student class ls.append(ob)

1. Display – This method displays the details of every student.

# Function to display student details def display(self, ob): print("Name : ", ob.name) print("RollNo : ", ob.rollno) print("Marks1 : ", ob.m1) print("Marks2 : ", ob.m2) print("\n")

1. Search – This method searches for a particular student from the list of students. This method will ask the user for roll number and then search according to the roll number

# Search Function def search(self, rn): for i in range(ls.__len__()): # iterate through the list containing # student object and checks through # roll no of each object if(ls[i].rollno == rn): # returns the object with matching # roll number return i

1. Delete – This method deletes the record of a particular student with a matching roll number.

# Delete Function def delete(self, rn): # Calls the search function # created above i = obj.search(rn) del ls[i]

1. Update – This method updates the roll number of the student. This method will ask for the old roll number and new roll number. It will replace the old roll number with a new roll number.

# Update Function def update(self, rn, No): # calling the search function # of student class i = obj.search(rn) ls[i].rollno = No

Below is the implementation of the above approach:
