My code is generating error prompt


#1

My code is generating error prompt . Please , help me look it up.
Here is my code:

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)
average = total / len(numbers)
return average

""" This function get average for each students and return
the final score for each student"""

def get_average(student):
homework = average(student["homework"])
tests = average(student["tests"])
quizzes = average(student["quizzes"])

return (0.1*homework + 0.3*quizzes + 0.6*tests)

""" This function determine the grade for each score passed as an argument"""

def get_letter_grade(score):

if score >= 90:
    return "A"

elif score >= 80 and score < 90 :
    return "D"        

elif score >= 70 and score < 80 :
    return "C"

elif score >= 60 and score < 70 :
    return "D"

else:
    return "F"

def get_class_average(students):

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

print get_class_average([lloyd,alice,tyler])

print get_letter_grade(get_class_average)

Here is the error message:
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


8. Part of Whole, returned average as 91.15 instead of 85.85 expected
9.How is every body doing?

Here is my code. Take a look and see where you did wrong :slightly_smiling:

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)
return total/len(numbers)

def get_average(student):
homework=average(student["homework"])
quizzes=average(student["quizzes"])
tests=average(student["tests"])

return 0.10*average(student["homework"])+ \
0.30*average(student["quizzes"])+ \
0.60*average(student["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"

def get_class_average(students):
results = []
for student in students:
get_average(student)
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))

Did you type your code exactly like this (in terms of indentations):

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)
    average = total / len(numbers)
    return average

""" This function get average for each students and return
the final score for each student"""

def get_average(student):
    homework = average(student["homework"])
    tests = average(student["tests"])
    quizzes = average(student["quizzes"])

    return (0.1*homework + 0.3*quizzes + 0.6*tests)

""" This function determine the grade for each score passed as an argument"""

def get_letter_grade(score):

    if score >= 90:
        return "A"

    elif score >= 80 and score < 90 :
        return "D"        

    elif score >= 70 and score < 80 :
        return "C"

    elif score >= 60 and score < 70 :
        return "D"

    else:
        return "F"

def get_class_average(students):

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

Because that worked for me

This was extremely helpful. I kept getting an 'invalid syntax' error at the line I had put return average(results) on. The problem was actually that I had just forgotten to make a list of the students' names and then print the output of the get_class_average function.
