Add your function below!

def average(numbers):
total=sum(numbers)
total=float(total)
return(total/len(numbers))
numbers=[2,4,6]
print (average(numbers))

student=[lloyd,alice,tyler]

def get_average(student):
for i in student:
a=average(student["homework"])
b=average(student["quizzes"])
c=average(student["tests"])
total=(a*0.10)+(b*0.30)+ (c*0.60)
return(total)
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(tyler))
def get_class_average(students):
results=[]
students=["Lloyd","Alice","Tyler"]
for student in students:
a=get_average(student)
results.append(a)
return average(results)


#2

all the return statements in this function should be in string form,


And also put this array storing all your dictionaries outside and before any functions,

should be here ,

#last dict closing bracket
}

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

#first function
def average(numbers):

#3

HI bandit ..., STRING FORM MEANS? WHAT DOES IT MEAN?


#4

do as mentioned by @bandit
and also remove this line from above code..
students=["Lloyd","Alice","Tyler"]


#5

Like this,

if score>=90:
   return "A" #note the quotation marks

Have you also done this,

And also put this array storing all your dictionaries outside and before any functions,

students=["Lloyd","Alice","Tyler"]

should be here ,

#last dict closing bracket
}

students = [lloyd,alice,tyler] #no quotation marks just as their names lloyd, alice, tyler

#first function
def average(numbers):

#6

They're variables(lloyd,alice and tyler) so they should not be surrounded by quotes?


#7

Dictionaries you mean,

and noted that just corrected my reply, thanks for pointing it out. :grin:
