Oops, try again. get_class_average([alice]) returned 83.8666666667 instead of 91.15 as expected


It should be 91.15

Hi @lharnett ,

There are a couple of things you should check.

Review what you were asked to do in Exercise 3: Put It Together. Are the names of variables in your code still consistent with what was done in that exercise?

You have this function header ...

def get_class_average(students):

Does this loop header use the information that is passed to the function via its parameter, or does it access a global variable instead? ...

for student in classlist:
