Oops, try again. get_class_average([alice, lloyd]) resulted in an error: 'float' object has no attribute 'append'


#2

Anyone have the idea to deal with ?


#3

This is not allowing any different lists to be passed in.


#4

what that means for different lists? even I remove the list, still meet same problem.

Add your function below!

def average(numbers):
total = sum(numbers)
total = float(total) / len(numbers)
return total
def get_average(student):
homework = average(student["homework"])
homework = average(student["quizzes"])
homework = average(student["tests"])
return .1 * average(student["homework"]) + \
.3 * average(student["quizzes"]) + .6 * average(student ["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(get_average(lloyd))

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

    I am getting this error

Oops, try again. get_class_average([alice]) resulted in an error: list indices must be integers, not str


#6

students should be singular object, student.
