Ex 19: Student Grading System

Problem​

Build an academic grading system that calculates a student's grade based on their score and generates a formatted report.

Rules​

  • Define calculate_grade(score: int | float) -> str.
  • Define generate_student_report(name: str, score: int | float) -> str.
  • Ensure the name is properly capitalized in the final report.

Boilerplate​

Copy below code and paste to our IDE for head start.

# Write our code inside this function
def calculate_grade(score: int | float) -> str:
    pass # remove this

def generate_student_report(name: str, score: int | float) -> str:
    pass # remove this

# Call with test data
print(generate_student_report("aman", 80))

Expected Output​

Aman has scored 80 and received grade B

def calculate_grade(score: int | float) -> str:
    if score >= 90:
        return "A"
    elif score >= 75:
        return "B"
    elif score >= 60:
        return "C"
    elif score >= 40:
        return "D"
    else:
        return "F"

def generate_student_report(name: str, score: int | float) -> str:
    # Capitalize name and call the grade function
    grade = calculate_grade(score)
    return f"{name.title()} has scored {score} and received grade {grade}"

# Test data
print(generate_student_report("aman", 80))

Details​

Breaking down complex tasks into smaller, specialized functions (like separating grading from reporting) is a fundamental practice in clean coding. It makes our code easier to test and maintain.
