9.Student becomes a teacher


#1



I am not stuck, just have a question about:
students=[lloyd,alice,tyler]
print get_class_average(students)
print get_letter_grade(get_class_average(students))

Why to do it as above, when we can write:
print get_class_average([alice,lloyd, tyler])
print get_letter_grade([alice,lloyd, tyler])

Second worked in section 8, but did not in 9


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 = sum(numbers)
    total = float(total)
    total = total/len(numbers)
    return total
def get_average (student):
    homework = average(student['homework'])
    quizzes = average(student['quizzes'])
    tests = average(student['tests'])
    return homework * 0.1 + quizzes * 0.3 + tests * 0.6
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 student in students:
        results.append(get_average(student))
    return average(results)
students=[lloyd,alice,tyler]     
print get_class_average(students)
print get_letter_grade(get_class_average(students))

Good thing this is a moot question. The SCT sent its own list to the program to test it. It wouldn't matter what we sent in out own tests. This is nitpicking, as I see it.
