Oops, try again.
It looks like Lloyd is not in the students list.


i expect the list works
instead of students = [lloyd, alice, tyler]
i don't understand why should i put variable in the list instead of string.


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']

This a list of strings. Remove quotes so it is a list of identifiers.

Thanks, it is new knowledge :relaxed:

students[0] is to lloyd as students[1] is to alice as students[2] is to tyler.

In truth, we have not actually inserted the dictionaries into the list, only their object references. The dictionaries remain where they are, in a singular instance.

The advantage we gain by storing a reference to each standalone dictionary is iterating through all of them with one convenient list.
