STUDENT BECOMES THE TEACHER For the Record


#1

hello. I need some help with my code, since i am doing everything it says in the instructions. I also change the strings. here is my 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]
}
students=[lloyd, alice, tyler]
for student in students:
print students[“name”]
print students[“homework”]
print students[“quizzes”]
print students[“tests”]

the error is as followed Traceback (most recent call last):
File “python”, line 21, in
TypeError: list indices must be integers, not str

any tips would be helpful.


#2

here:

print students[“name”]

students is a list, lists can’t only be accessed by index

clearly students isn’t what you should use here, what should you use?


#3

i had to change it to student


#4

yes you did, you understand why?


#5

because it was student in students, not the students itself. so it is pulling the individual students, instead of trying to pull all.
