Student Become Teacher(Part of the Whole)

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

As per the instruction it should return the total average which is 83.87 same output from my code.

``````lloyd = {
"name": "Lloyd",
"homework": [90.0, 97.0, 75.0, 92.0],
"quizzes": [88.0, 40.0, 94.0],
"tests": [75.0, 90.0]
}
alice = {
"name": "Alice",
"homework": [100.0, 92.0, 98.0, 100.0],
"quizzes": [82.0, 83.0, 91.0],
"tests": [89.0, 97.0]
}
tyler = {
"name": "Tyler",
"homework": [0.0, 87.0, 75.0, 22.0],
"quizzes": [0.0, 75.0, 78.0],
"tests": [100.0, 100.0]
}

def average(numbers):
total = float(sum(numbers))
avg = total/len(numbers)
return avg
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
sum_wavg = homework*0.1+quizzes*0.3+tests*0.6
return sum_wavg
if score >= 90 :
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"
student_list = [lloyd,alice,tyler]
def get_class_average(students):
results = []
for x in student_list:
results.append(get_average(x))
print results
return average(results)
print get_class_average(student_list)``````

Your function takes one parameter - `students`.

But in the body of the function you are getting data from the global variable called `student_list`

This is the problem.

You should iterate through data passed as an argument. Instead of `for x in student_list` you should use `for x in students`.

Result of the function should be dependent upon passed arguments. In your case - returned value is always the same, no matter what the argument is.
