Project: a grade report

Use everything you learned in a small real program.

10 minutes1 games

You have student marks in a dictionary. Write a program that prints each student's mark and grade, then the average and the top student. You'll use a dictionary, for, if, a function and f-strings.

Python

marks = {"Ali": 88, "Mona": 95, "Omar": 72, "Sara": 64}

def grade(m):
    if m >= 85:
        return "A"
    elif m >= 70:
        return "B"
    return "C"

for name, m in marks.items():
    print(f"{name}: {m} ({grade(m)})")

average = sum(marks.values()) / len(marks)
best = max(marks, key=marks.get)
print(f"Average: {average:.1f}")
print(f"Top student: {best}")
