How is Everybody Doing?


Oops, try again. One of the following is missing or broken when we tried to use it: alice, lloyd, tyler, students, get_class_average, get_letter_grade

I don't see any error there so expect program to execute successfully. please help


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(numbers):
    total = float(sum(numbers))
    return total / len(numbers)
    
def get_average (student):
    homework = average(student["homework"])
    quizzes = average (student["quizzes"])
    tests = average (student["tests"])
    return  0.1 * homework + 0.3 * quizzes + 0.6 * 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"
    
    
#print get_letter_grade(get_average(lloyd))

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

class_avg = get_class_average([lloyd,alice,tyler])

print get_letter_grade( class_avg)

Hi, @pankajtayade ,

Instead of this ...

class_avg = get_class_average([lloyd,alice,tyler])

... you should should have this global assignment statement ...

students = [lloyd, alice, tyler]

... and use the students variable as the argument to get_class_average.

The assignment statement was added in Exercise 3: Put It Together, but that statement got lost later on.
