# 9/9 "One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade"

#1

HI! I have been following these python tutorials and I am now stuck.

Here is 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]
}

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

students = ["lloyd","alice","tyler"]

if (score >= 90):
return "A"
elif (score >= 80 and score < 90):
return "B"
elif (score >= 70 and score < 80):
return "C"
elif (score >= 60 and score < 70):
return "D"
else:
return "F"
for student in students:

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

You have ...

students = ["lloyd","alice","tyler"]

... but students should be a list of the three variables that refer to the dictionaries for each student. Instead, the above is a list of three strings. This is what is needed ..

students = [lloyd, alice, tyler]

I have taken your advice yet it still has not worked for me @appylpye

#4

I have realised that my average function was missing so I added it back in, however, this still hasn't fixed the problem!

#5

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