# How Everybody Doing: Error

#1

Hey guys can anyone help me? me code looks as follows:

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

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

But i get the message: One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade. any suggestions?

Hi @youngbonaparte, All the variables that the error message lists (alice, lloyd, tyler, students, get_class_average, get_letter_grade) should be in the global scope, not inside any function.

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

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
weighted = (homework *0.1) + ( quizzes *0.3) + (tests *0.6)
return weighted

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"
print
print "lloyd"
print
print "alice"
print
print "tyler"

def get_class_average(students):
results = []
#students = [lloyd, alice, tyler]
for student in students:
students = get_average(student)
results.append(get_average(student))
return average(results)

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

after many trials, the students = [lloyd, alice, tyler] makes the code work
