# I donno whats wrong in this.. can anyone help me

**stetim94**#2

are you sure your indention is right?

here:

`students = ["lloyd", "alice", "tyler"]`

you stored strings in your list, why?

lets see what happens we put this to the test:

```
def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
"""return homework
return quizzes
return tests"""
return 0.10 * homework + 0.30 * quizzes + 0.60 * tests
print get_average("lloyd")
```

this will throw an error, you should supply the dictionary `lloyd`

as argument, so your students list should contain dictionaries also, not strings

If you need more help, post an updated version of your code

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 homework

return quizzes

return tests"""

return 0.10 * homework + 0.30 * quizzes + 0.60 * tests

def get_letter_grade(score):

if score >= 90:

return "A"

elif score >=80 and score < 90:

return "B"

elif score >= 70 and score < 80:

return "C"

elif score >= 60 and score < 70:

return "D"

else:

return "F"

return get_average(lloyd)

students = [lloyd, alice, tyler]

def get_class_average(students):

results = []

for student in students:

results.append(get_average(student))

return average(results)

print get_class_average(students)

print get_letter_grade(get_class_average(students))

i edited that but it is throwing an error One of the following is missing or broken when we tried to use it: lloyd, alice, tyler, students, get_class_average, get_letter_grade

**mtf**#4

For the sake of organization, can we place the students list in the data area of the source code, just after all the dictionaries that it references?

```
lloyd = {}
alice = {}
tyler = {}
students = [lloyd, alice, tyler]
```

noo i found the error, my mistake is after get_letter_grade function instead of printing that i accidentally wrote return.. by the way thanks fr helping..

Hi I have added comments/description inside your original code sample(below) where you have to perform changes to run this properly.

```
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 homework
return quizzes

return 0.10 * homework + 0.30 * quizzes + 0.60 * tests
def get_letter_grade(score):
if score >= 90:
return "A"
elif score >=80 and score < 90:
return "B"
elif score >= 70 and score < 80:
return "C"
elif score >= 60 and score < 70:
return "D"
else:
return "F"
"""Instead of 'return' type 'print' and remove spaces from starting. """
return get_average(lloyd)
""" Remove double quotes from the list students[] as they are dictionaries and not string. """
students = ["lloyd", "alice", "tyler"]
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
return average(results)
""" Remove spaces before print statement and indent it correctly"""
print get_class_average(students)
print get_letter_grade(get_class_average(students))
```
