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]

}

students= [tyler, lloyd, alice]

for student in students:

def average(student):

total= float(sum(student))

total= total/float(len(student))

return total

def get_average(student):

homework=average(student[“homework”])

quizzes=average(student[“quizzes”])

tests=average(student[“tests”])

weighted_total= homework*.1 + quizzes*.3 + tests*.6

return weighted_total

student.update({“weighted_total”: weighted_total})

return student

print average(tyler[“homework”])

print get_average(alice)

print lloyd

The output:

46.0

91.15

{‘quizzes’: [88.0, 40.0, 94.0], ‘tests’: [75.0, 90.0], ‘name’: ‘Lloyd’, ‘homework’: [90.0, 97.0, 75.0, 92.0]}

The details:

I completed the objective for the lesson, but I’m trying to get the program to created a new item in each dictionary and then store the weighted average in that new item.
