How is everybody doing?


#1



lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

Add your function below!

def average(numbers):
total = sum(numbers)
total = float(total)
total = total / len(numbers)
return total
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return 0.1 * homework + 0.3 * quizzes + 0.6 * tests
def get_letter_grade(score):

if score >= 90:
    return "A"
elif score >= 80:
    return "B"
elif score >= 70:
    return "C"
elif score >= 60:
    return "D"
else:    
     return "F"

print get_letter_grade(get_average(lloyd))
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)
students = [lloyd, alice, tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))

Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

i am not able to understand whts wrong?...

Replace this line with your code.

This needs to be a global variable meaning outside any function or dictionary,

Place it right after,


#3

nothing happened...still the same error

Hi @hitesh3371,

there is a bit of conflict, here.

It should be:

print get_letter_grade(lloyd)

So, in full, you have:

lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],
    "quizzes": [88.0, 40.0, 94.0],
    "tests": [75.0, 90.0]
}
alice = {
    "name": "Alice",
    "homework": [100.0, 92.0, 98.0, 100.0],
    "quizzes": [82.0, 83.0, 91.0],
    "tests": [89.0, 97.0]
}
tyler = {
    "name": "Tyler",
    "homework": [0.0, 87.0, 75.0, 22.0],
    "quizzes": [0.0, 75.0, 78.0],
    "tests": [100.0, 100.0]
}

def average(numbers):
    total = sum(numbers)
    total = float(total)
    total/=(len(numbers))
    return total
    

def get_average(student):
    homework = average(student["homework"])
    quizzes = average(student["quizzes"])
    tests = average(student["tests"])
    return 0.10*homework + 0.30*quizzes + 0.60*tests

def get_letter_grade(score):
    if score >= 90:
        return "A"
    elif score >= 80:
        return "B"
    elif score >= 70:
        return "C"
    elif score >= 60:
        return "D"
    else:
        return "F"
print get_letter_grade(lloyd)

def get_class_average(students):
    results = []
    for student in students:
        results.append(get_average(student))
    return average(results)

students = [lloyd, alice, tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))

After fixing this,

And removing this from the function,

Your code should work. :slight_smile:
