Why can't I put the 'print' into the functions themselves?


#1


Hi everyone. I have a question about the below exercise.



Here's my code for this exercise. I've completed this exercise, so I know what you have to do, but I don't know why the below doesn't work. As you can see, I've added 'print' within the functions below.

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):
k = sum(numbers)
total = float(k) / len(numbers)
return total
print total

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests = average(student["tests"])
return 0.3 * quizzes + 0.1 * homework + 0.6 * tests

def get_letter_grade(score):
if score >= 90:
return 'A'
print 'A'
elif 80 <= score < 90:
return 'B'
print 'B'
if 70 <= score < 80:
return 'C'
print 'C'
elif 60 <= score < 70:
return 'D'
print 'D'
else:
return "F"
print 'F'

get_letter_grade(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 average(results)

get_class_average(students)

get_letter_grade(get_class_average(students))

Can anyone help me understand why this doesn't work? I know that you have to end with:

print get_class_average(students)

print get_letter_grade(get_class_average(students))

But why is adding the 'print' command into the functions themselves insufficient?

Thanks in advance for any help.

hey it should look like this you added to many print functions

def average(numbers):
total= sum(numbers)
total = float(total)/ len(numbers)
print total
return total

def get_average(student):
homework = average(student["homework"])
quizzes = average(student["quizzes"])
tests= average(student["tests"])
print homework, quizzes, tests
return homework * 0.1 + quizzes * 0.3 + tests * 0.6

def get_letter_grade(score):
score = int(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))
print get_letter_grade(get_average(alice))
print get_letter_grade(get_average(tyler))

student = [lloyd, alice, tyler]
def get_class_average(students):
results = []
for student in students:
results.append(get_average(student))
print results
return average(results)

Thank you. I did get it to work fine just by adding 'print' to the last two lines. That being said, since 'print' was in the previous functions, I don't understand why it wouldn't work before. Do you have any advice on that?

Honestly ive had the same problems before it bugs out sometimes or you have it indented wrong
