def get_class_average(students):

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?
