How is Everybody doing? Can't solve


#1




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 expected the code to work and print.


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) / float(len(numbers))
    return total
def get_average(student):
    homework = average(student["homework"])* 0.1
    quizzes = average(student["quizzes"])* 0.3
    tests = average(student["tests"])* 0.6
    avrg = homework + quizzes + tests
    return avrg
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"
    elif score < 60:
        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)   
    get_average(student)
    students = ["lloyd", "alice", "tyler"]
    print get_class_average(students)
    print get_letter_grade(get_class_average(students))

The same problem. Mine too shows an error message.

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]
}

student = [lloyd,alice,tyler]
def average(numbers):

total = sum(numbers)
total = float (total)
final = total / len(numbers)
return final

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
final_sum = 0.1*homework + 0.3*quizzes + 0.6*tests
return final_sum

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"

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

finalll = get_class_average(student)
print finalll
print get_letter_grade(finalll)


#3

Students- list is made of dictionaries, not strings, so remove the inverted commas.


#4

Also you should make students- list and print the averages outside the function, of course, so remove the spaces. :slight_smile:
