Student Becomes the Teacher(Part of the Whole)


#1

Here is my code.I cannot get correct result.I am getting error like this
Oops, try again. get_class_average([alice, lloyd]) returned 91.15 instead of 85.85 as expected

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!

total = 0
def average(numbers):
total = sum(numbers)
total = float(total)
total = total / len(numbers)
return total
def get_average(student):
homework = average(student["homework"]) * .1
quizzes = average(student["quizzes"]) * .3
tests = average(student["tests"]) * .60
return quizzes+homework+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"
print get_letter_grade(average(lloyd))
def get_class_average(students):
results=[]
for student in students:
results.append(get_average(student))
results = average(results)
return results

students =[lloyd,alice,tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))
