8. Part of the whole


#1

hi there I have tried coding this twice and I am still getting the #91.15 instead of 85.85, can anyone see what I'm doing wrong?
kind regards
-M

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]
}
students = ( lloyd, alice, tyler)

Add your function below!

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

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

def average(numbers):
total = sum(numbers)
total = float(total)
total = total / len(numbers)
return total
"""def get_class_average(students):
results=[]
for students in students:
classavg = get_average(students)
results.append(classavg)
return average(results)"""

91.15.....85.85?

Perhaps if the code in your post was formatted correctly, people would be able to tell.

Add prints in your code to follow along in what it does.

This is the part I missed :smile: Thank you !
