Student Becomes the Teacher part 9

#1

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

``````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 = sum(numbers)
total = float(total)
avg = total / len(numbers)
return avg

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
tot_avg = 0.10 * homework + 0.30 * quizzes + \
0.60 * tests

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

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

print get_class_average(s)

#2

here:

``print get_letter_grade(print get_class_average(s)``

why two `print` keywords? One is enough at beginning of the line, also look at your parentheses on this line

finally `s` is undefined, it should be students, which is a list you build in 3. put it together, which is currently missing. Revisit 3. put it together if you don't remember what was in the list

#3

I see that mistake with print i just copied the above line to input it as argument to the next line. sorry about that.
Also about creating s should it be with quotations or without.
Thanks

#4

gives an average value of : 83.66667

Still gives an error

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

Should say exercise completed

``````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 = sum(numbers)
total = float(total)
avg = total / len(numbers)
return avg

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
tot_avg = 0.10 * homework + 0.30 * quizzes + \
0.60 * tests

if score >= 90:
return "A"
elif score >= 80:
return "B"
elif score >= 70:
return "C"
elif score >= 60:
return "D"
else:
return "F"

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

s = [lloyd, alice, tyler]

print get_class_average(s)

#5

the list should be named students, not s

#6

only then it will work ?

#7

yes, the exercise the list is present under that name

#8
