Hey got a bit stuck on this one hoping someone can see where i've gone wrong. i tried calling the functions and printing out the current student name (curr) but this lso caused an error.

the error is "function object has no attibute '____getitem____' but i can't see which attribute isn't getting passed

many thanks in advance for any help

sorry can't work out how to reindent code and won't let me upload txt version

```
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],
