Part of the Whole


#1

Basically, my problem is this. I try to add the function def get_class_average(students):
students = ["lloyd","alice","tyler"]
results = []
for student in students
get_average(student)
results.append()
return average(results)

But then when I run it I get the error: File "python", line 40
for student in students
^
SyntaxError: invalid syntax

I've tried moving the "students" list to outside the function with the same effect. The problem I have is that it doesn't seem to recognize the list and I'm not sure how to force it to.

Here is my complete 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]
}

Add your function below!

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"

get_letter_grade(get_average(lloyd))
print get_letter_grade

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

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

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
