Introduction
The Python Grading System Project is an excellent beginner-friendly programming activity that teaches students how to use conditional statements in Python. This project helps students understand how schools assign grades based on marks and demonstrates how the same process can be automated using programming.
In this Python Grading System Project, students enter their marks, and the program automatically assigns a grade using if, elif, and else statements. The project introduces important concepts such as classes, objects, user input, and decision-making logic.
As part of Grade 9 STEM Activities, this project encourages logical thinking, problem-solving, and hands-on coding practice.

What is a Python Grading System?
A grading system is used to evaluate student performance based on marks obtained in examinations.
The Python Grading System Project automates this process by checking marks against predefined grading criteria and displaying the corresponding grade.
Instead of manually determining grades, the program performs the evaluation instantly and accurately.
Learning Objectives
By completing this Python Grading System Project, students will learn:
- Conditional Statements (
if,elif,else) - Classes and Objects
- User Input Handling
- Decision-Making Logic
- Object-Oriented Programming Basics
- Python Programming Fundamentals
- Problem-Solving Skills
These concepts form an important foundation for future programming projects.
Software Requirements
This project requires only software tools.
| Software | Purpose |
|---|---|
| Python | Programming Language |
| VS Code | Writing and Running Code |
| Computer/Laptop | Project Development |
Students may also use Python IDLE, PyCharm, or Thonny IDE.
Understanding Conditional Statements
Conditional statements allow a program to make decisions based on specific conditions.
if Statement
The if statement checks the first condition.
if marks >= 95:
elif Statement
The elif statement checks additional conditions if the previous condition is false.
elif marks >= 90:
else Statement
The else statement executes when none of the previous conditions are true.
else:
These statements are the core of the Python Grading System Project.

Project Algorithm
Follow these simple steps:
Step 1
Create a Student class.
Step 2
Accept marks as input from the user.
Step 3
Use conditional statements to check the marks range.
Step 4
Assign grades based on the conditions.
Step 5
Display the grade.
Step 6
Test the program with different marks.
Python Grading System Project Code
Python code implementing a grading system using classes and conditional statements.
class Student:
def calculate_grade(self, marks):
if marks >= 95:
return “A+”
elif marks >= 90:
return “A”
elif marks >= 80:
return “B”
elif marks >= 65:
return “C”
else:
return “D”
student = Student()
marks = int(input(“Enter Marks: “))
grade = student.calculate_grade(marks)
print(“Grade:”, grade)
Code Explanation
Creating the Class
class Student:
A Student class is created to organize the grading logic.
Creating the Method
def calculate_grade(self, marks):
This method receives marks and determines the grade.
Checking Marks
if marks >= 95:
The program checks whether the marks meet the highest grade requirement.
Additional Conditions
elif marks >= 90:
The program continues checking other grading ranges.
Default Condition
else:
If none of the conditions are satisfied, a lower grade is assigned.
Displaying Output
print("Grade:", grade)
The final grade is displayed to the user.
Sample Output
Example 1
Enter Marks: 99
Grade: A+
Example 2
Enter Marks: 92
Grade: A
Example 3
Enter Marks: 85
Grade: B
Example 4
Enter Marks: 65
Grade: C
Example 5
Enter Marks: 25
Grade: D
These outputs demonstrate that the Python Grading System Project correctly evaluates different score ranges.
