string indices must be int not str for get_class_average(asdf) function call


dont know why thats giving a problem

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]
}

# Add your function below!
def average(num):
    total = sum(num)
    average = float(total)/len(num)
    return average

def get_average(stude):
    home = average(stude["homework"])
    qui = average(stude["quizzes"])
    tes = average(stude["tests"])
    return 0.10*home + 0.30*qui + 0.60*tes
    
def get_letter_grade(sc):
    if(sc>89):
        return "A"
    elif(sc>79):
        return "B"
    elif(sc>69):
        return "C"
    elif(sc>59):
        return "D"
    else:
        return "F"
get_letter_grade(get_average(lloyd))
asdf =  ['lloyd','alice','tyler']

def get_class_average(classs):
    results = []
    for student in classs :
        results.append(get_average(student))
        
get_class_average(asdf)
#get_average("lloyd")


#2

yes u have more than on mistake.

asdf = [lloyd, alice, tyler]

this are defined variable and no strings!


#3

and you forgot the return statement

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

now it works
