How is Everybody doing?


#1

I find myself a t a cross roads ...if the error is to be believed I messed up some where waaay back .
The error is " 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 "

Can someone kindly point me in the right direction

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 0.1 * average(student["homework"]) + \
0.3 * average(student["quizzes"])+ 0.6* 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"
elif score <= 59:
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)

print get_class_average(student)
print get_letter_grade(student)

It looks like there is no students list. This is asked for in one of the lessons.

students = [ lloyd, alice, tyler ]

Is all redundant since everything is computed in the return statement.

The alternative is to replace the return statement with their sum.

return homework + quizzes + tests

Ok I just found out some code was missing as you suggested and even though in the previous excercises I had put it in ...anyway ....copied and pasted it in now I'm getting oops.... seems like the class average was not printed out ...83.333... or so

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]
}
students = [lloyd, alice, tyler]

for student in students: 
    print student["name"]
    print student["homework"]
    print student["quizzes"]
    print student["tests"]
# 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 0.1 * average(student["homework"]) + \
    0.3 * average(student["quizzes"])+ 0.6* 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"
    elif score <= 59:
        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(get_letter_grade(score)) 
    
    print get_class_average(students)
    print get_letter_grade(get_average(students)

#5

Missing parenthesis to close get_letter_grade() parameter.

You still need decide what to do with get_average(). Either remove the redundant code or change the return statement.
