# 8. part of the whole

#1

Oops, try again. alice does not seem to contain the correct dictionary, it should contain: {'quizzes': [82.0, 83.0, 91.0], 'tests': [89.0, 97.0], 'name': 'Alice', 'homework': [100.0, 92.0, 98.0, 100.0]}

I don't know what is wrong with my code. Plz help me.

``````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)

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

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:
results.append(get_average(student))

return average(results)

print get_class_average([alice,tyler])``````

that's strange, try refreshing the page

#3

Did the console show any error messages??

Oops, try again. alice does not seem to contain the correct dictionary, it should contain: {'quizzes': [82.0, 83.0, 91.0], 'tests': [89.0, 97.0], 'name': 'Alice', 'homework': [100.0, 92.0, 98.0, 100.0]}

is the error message

#5

No, I didn't mean that. I asked if there were any syntax errors or something.

#6

I have completed this exercise. As the code is really big it might be difficult to find out what happened. I can give my code if you want.

#7

could you give me that code? plz

#8

This is the 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]
}

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

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

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:
results.append(get_average(student))
return average(results)

print get_class_average([alice, tyler])``````

#9

Doesn't work for me and i did it exactly like yours

#10

Never mind, I wrote result.append(get_average(student)) instead of results.append(get_average(student))
