8: Part of the Whole


#1

OK, time for me to get help...

My code calculates precisely what it is told to calculate - the class average.
Problem is - the error I get seems to want only "Alice"'s average.

I calculated it manually and my code is correct - it actually works perfectly well.

Did I get it wrong?!

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]
}

class_list = [lloyd, alice, tyler] # 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"]) * 0.10
quizzes = average(student["quizzes"]) * 0.30
tests = average(student["tests"]) * 0.60
return homework + quizzes + 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 class_list:
item = get_average(student)
results.append(item)
return average(results)

P.S. the posting removed all the indents. The code is indented correctly.

This is the code that i used:

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

return average(results)

#5

Can you tell us what exatcly says error message?
Also, to keep indents you have to select pasted code and press Ctrl + Shift + C


#6

This code works well for me.

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

return average(results)

#7

yeah, once I changed it from "class_list" to "students", my code was fine... Freaky...

You shouldn't have defined the variable class_list on line twenty. I believe you miss read the instructions. 03: For each student item in the class list, calculate get_average(student) and then call results.append() with that result. The instructions where trying to emphasize that you iterate through the class_list or in your case the list students.
