Add your function below!

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 homework * 0.1 + quizzes *0.3 + tests * 0.6

def get_letter_grade(score):
score = float(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(get_average(student)

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

I keep getting this error:
File "python", line 48
def get_class_average(students):
^
SyntaxError: invalid syntax

I can't seem to figure out what the issue with my syntax is, all of my indentation and punctuation seems correct. Thanks in advance for the help!


#2

The error is actually the line above. It is missing a right parens )

print get_letter_grade(get_average(student))

#3

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

with this error:
Traceback (most recent call last):
File "python", line 46, in
NameError: name 'student' is not defined


#4

    return get_average(results)   # ?

Is this what you are aiming for?
