Add your function below!

def average(numbers):
total = sum(numbers)
total = float(total) / len(numbers)
return total
def get_average(students):
homework = student["homework"]
quizzes = student["quizzes"]
tests = student["tests"]
return 0.1 * average(homework) + 0.3 * average(quizzes) + 0.6 * average(tests)
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(80)
def get_class_average(students):
results=[]
for student in students:
get_average(student)
results.append(get_average(student))
return average(results)

I have error like Oops, try again. get_class_average([alice]) resulted in an error: global name 'student' is not defined
pls help friends

If you call your function the same way as the error message mentions then you should get the same error message in the console, but this time including a line number of where the exception happened.

I think the problem is the function named "get_average(students)", you can try to change it to get_average(student), which is same with what in the function,like
def get_average(student):
homework = student["homework"]
quizzes = student["quizzes"]
tests = student["tests"]
return 0.1 * average(homework) + 0.3 * average(quizzes) + 0.6 * average(tests)
